Synergistic coupling of FeS/FeNi nanoparticles with 3D N, S dual-doped porous carbon network for bifunctional ORR/OER electrocatalysts and zinc-air batteries

Wenji Liang,Junwei Shi,Zhenhua Qin,Jinguang Cai,Yun He,Jianfen Li

Exploring efficient and durable non-noble metal catalysts toward oxygen reduction/evolution reaction (ORR/OER) is of practical significance in advancing Zn-air batteries. Herein, we introduce a three-dimensional (3D) bifunctional electrocatalyst (Fe/Ni@NSC) consisting of N, S-dual doped mesoporous carbon nanosheets/carbon nanotubes embedded with abundant FeS/FeNi nanoparticles and Fe/Ni-N x sites by integrating rod-like ZIF-L@S-g-C 3 N 4 with Fe/Ni-phen complex and subsequent pyrolysis. The 3D structure not only offers a high surface area for active sites but also accelerates O 2 transport/charge transfer. Leveraging the synergistic effect of the 3D porous carbon network and multiple active sites, Fe/Ni@NSC exhibited outstanding activities in both ORR (half-wave potential, 0.868 V) and OER (overpotential, 317 mV at 10 mA cm −2 ), indicating a low potential gap of 0.679 V, outperforming the Pt/C + RuO 2 benchmarks (0.695 V). The Zn-air batteries based on Fe/Ni@NSC achieved a promising open circuit voltage (1.47 V), peak power density (172.59 mW cm −2 ), as well as long-term cycling stability (370 h). Furthermore, density functional theory (DFT) calculations also demonstrated that the interfacial electronic interaction between FeS and FeNi effectively boosted the bifunctional catalytic performance for ORR/OER. This study lays the foundation for designing low-cost and efficient 3D structure non-noble metal catalysts for more energy conversion and storage devices.

Synergizing the plasmonic and semiconductor properties of W18O49 for enhanced hydrogen evolution under broadband excitation

Zehong Xu,Weilong Liu,Wenhui Yue,Mengyuan Li,Shiqun Wu,Lingzhi Wang,Yikai Xu,Chunchun Li,Ziwei Ye,Jinlong Zhang

WO 2.72 , with its broad localized surface plasmon resonance (LSPR) response, holds significant potential for harvesting visible and near-infrared (NIR) solar radiation. However, due to its relatively low free electron density, its LSPR excitation intensity is inherently weaker compared to conventional plasmonic metals. In this study, we enhanced the LSPR response of WO 2.72 by coupling it with Au nanoparticles. Upon LSPR excitation, this hybrid structure enables efficient generation of hot electrons, which can be extracted by the surface-deposited CdS layer to drive hydrogen evolution reactions. Importantly, the incorporation of the CdS layer also leads to the formation of an S-scheme heterojunction between CdS and WO 2.72 due to their well-matched band structures. The formation of S-scheme heterojunction not only promotes more efficient UV-excited generation of photo electrons in WO 2.72 and CdS, but also prevents the mutual cancellation of hot electrons and photogenerated electrons due to interfacial band bending. This synergy ensures efficient generation and utilization of both hot electrons and photogenerated electrons, giving rise to an excellent hydrogen evolution rate of 165.5 ​mmol ​g −1 ​h −1 under the irradiation of the stimulated sunlight.

Heterointerface engineering and phosphorus doping dual-regulation enabled P-CoO/Co9S8@activated carbon for high-performance supercapacitors

Haoran Wang,Zuoyi Xiao,Siyu Gao,Haoran Zhang,Jianxi Zhang,Meijie Gao,Zizhen Yang,Yao Tong,Chuanyin Xiong,Junhong Fu,Shangru Zhai,Qingda An

Commercial AC is employed as the support to fabricate the P-CoO/Co 9 S 8 @AC electrode. • The formation of P-CoO/Co 9 S 8 @AC realizes the deep coupling of macroscopic structural buffering and atomic-scale electronic regulation. • The synergy of heterointerface and P doping enhances OH − adsorption and accelerates redox reaction rate. • The ASC achieves a high energy density of 90.4 Wh kg −1 at 750 W kg −1 . Supercapacitor performance is largely determined by electrode materials. Transition metal compounds (TMCs) have high theoretical capacities but suffer from sluggish charge transport and volume-induced structural degradation, which limits their practical applications in energy storage. To overcome the inherent bottlenecks of TMCs in energy storage, this work reports a novel dual-regulation strategy to construct a P-doped CoO/Co 9 S 8 heterostructure anchored on activated carbon (P-CoO/Co 9 S 8 @AC). The formation of the P-doped CoO/Co 9 S 8 @AC heterostructure enables close coupling between macroscopic structural buffering and atomic-scale electronic modulation. Introducing activated carbon (AC) suppresses particle agglomeration and buffers volume expansion, while the synergistic effect of heterointerface engineering and P doping significantly reduces the charge-transfer resistance to 0.27 Ω. Benefiting from these multidimensional advantages, the as-prepared material delivers a specific capacity of 1697.3 C g −1 (3394.6 F g −1 ) at 1 A g −1 , outperforming previously reported nickel sulfide/nickel oxide heterostructures (2278 F g −1 ) and P-doped ternary cobalt-based sulfide electrodes (2716 F g −1 ). Density functional theory (DFT) calculations show that the P-doped heterostructure has an OH − adsorption energy of −4.82 eV and an upshifted d-band center, thereby improving intrinsic conductivity and OH − interfacial adsorption. Furthermore, the assembled hybrid supercapacitor (HSC) achieves a high energy density of 90.4 Wh kg −1 at a power density of 750 W kg −1 , while retaining 86.1% of its capacity after 20,000 cycles. This study provides a design strategy for constructing high-performance composite electrodes by integrating heterointerface engineering and heteroatom doping. A novel strategy is reported to construct P-CoO/Co 9 S 8 @AC. DFT calculations demonstrate that the synergistic effect of CoO/Co 9 S 8 heterostructure formation and P doping strengthens OH − adsorption and boosts the electrochemical performance.

Highly selective NO2 sensing for mobile on-site monitoring enabled by a dual-sensitization mechanism in palladium sulfide-based nanocomposites

Yongjing Guo,Hangshuo Feng,Qiuni Zhao,Shenghui Guo,Renminxi Ou,Shunping Zhang,Zaihua Duan,Yi Xia,Zhen Yuan,Ming Hou,Li Yang,Huiling Tai

A sulfur vacancy-rich PdS/MoS 2 hierarchical heterostructures were synthesized via in-situ microwave-assisted method. • A dual-sensitization mechanism of synergistic enhancement of sulfur vacancy and heterojunction was proposed. • A mobile monitoring system is developed for on-site NO 2 tracking, enabling excessive NO 2 concentration warning. Developing high-selectivity and high-sensitivity nitrogen dioxide (NO 2 ) gas sensors, and explaining the complex underlying sensitization mechanisms remain critical challenges. Herein, we propose a dual-sensitization mechanism of synergistic enhancement of sulfur vacancy and heterojunction at composite interface to develop a high-performance NO 2 gas sensor at room temperature. A novel sulfur vacancy-rich palladium sulfide (PdS) nanocluster is synthesized via a microwave-assisted method, and it is further in situ decorated on molybdenum disulfide (MoS 2 ) nanoflowers to construct hierarchical heterostructure. The high selectivity of PdS/MoS 2 gas sensor is verified via experiment and density functional theory calculation. The PdS/MoS 2 composite system shows the highest adsorption energy (−1.89 eV) to NO 2 among various interfering gases, which further decreases to −2.11 eV after introducing sulfur vacancies. Meanwhile, the proposed dual-sensitization mechanism is based on “targeted electron-reflux” effect resulting from the synergistic action of sulfur vacancies and the p-p heterojunction, which modulates the interfacial carrier migration behaviors. Furthermore, a mobile NO 2 monitoring system is developed for on-site NO 2 tracking, which is equipped with the PdS/MoS 2 gas sensor, universal serial bus module, and smart phone, enabling real-time monitoring and excessive NO 2 concentration warning. This work proposes a research approach for complicated gas sensing mechanism, and provides an avenue for portable and intelligent gas detection.

Construction of Fe3S4/PDA/HA composites with enhanced interfacial effect for photo-Fenton degradation of tetracycline: Mechanism and toxicity assessment

Siyu Song,Yirou Hu,Fanglin Guo,Dan Li,Tao Wang,Wei Peng,Feigao Xu

Antibiotic pollution in aquatic environments poses critical ecological and health risks worldwide. In this study, a novel Fe 3 S 4 /PDA/HA (FPA) composite was designed as a heterogeneous photo-Fenton catalyst for peroxymonosulfate (PMS) activation to degrade tetracycline hydrochloride (TCH). The FPA catalyst was synthesized through a solvothermal route combined with polydopamine (PDA) coating and humic acid (HA) functionalization. Characterizations revealed that PDA and HA modification effectively suppressed nanoparticle agglomeration, reduced iron leaching, broadened the visible-light response, and accelerated Fe 2 + /Fe 3+ redox cycling. Under visible-light irradiation, the FPA/PMS system attained 86.8% TCH removal and 45.6% total organic carbon mineralization within 60 min, with a pseudo-first-order rate constant (0.06658 min −1 ) 2.72-fold higher than that of pure Fe 3 S 4 . The catalyst maintained excellent catalytic activity over a wide pH range (2–10) and showed strong resistance to common coexisting anions. After five cycles, TCH degradation efficiency remained above 87%, confirming excellent reusability. Quenching tests and electron paramagnetic resonance demonstrated that •OH, •O 2 ⁻, SO 4 •⁻, and 1 O 2 were generated, with 1 O 2 acting as the predominant reactive oxygen species. Liquid chromatography–mass spectrometry revealed three TCH degradation pathways, and ECOSAR toxicity analysis verified that most intermediates exhibited lower toxicity than the parent compound. This work provides a promising and stable photo-Fenton catalyst for efficient degradation of antibiotic pollutants and offers new insights into advanced oxidation processes for wastewater remediation.

Construction of GO/MoS2/TiO2 ternary heterojunction interfaces for synergistically enhanced electrochemical sensing of acetaminophen

Bao Jiang,Yanhui Niu,Xiuxin Jin,Yuntao Huang,Qin Hu,Yaxin Luo,Jialing Hua

Rational Interface Engineering: We successfully synthesized a GO/MoS 2 /TiO 2 ternary nanocomposite with carefully engineered heterojunction interfaces. This structure not only prevents the restacking of MoS 2 and aggregation of TiO 2 but also facilitates efficient charge separation and accelerates electron transfer rates compared to single or binary counterparts. • Significant Synergistic Enhancement: Rather than simply mixing components, our design yields a substantial improvement in electrochemical performance. The sensor exhibits a 2-fold increase in current response and a significantly lower detection limit compared to the individual MoS 2 electrodes. This result strongly validates the effectiveness of our interface engineering strategy in overcoming the intrinsic limitations of single-component materials. • Self-Cleaning and Anti-Fouling Capability: A distinct advantage of our ternary system is its excellent anti-fouling property. The incorporation of TiO 2 endows the sensor with self-cleaning capabilities (attributed to its photocatalytic activity/surface properties), effectively mitigating electrode passivation caused by the adsorption of oxidation products. This ensures superior operational stability and reproducibility, addressing a common bottleneck in APAP detection. • Practical Robustness: We successfully applied the sensor to the determination of acetaminophen in real pharmaceutical tablets and water samples with satisfactory recovery rates, proving its potential for practical applications in complex matrices. Efficient detection of acetaminophen (APAP) is critical for public health and environmental safety, but traditional electrochemical sensors often suffer from severe electrode passivation and ambiguous interfacial sensing mechanisms.To address these challenges, To address these fundamental challenges, this study constructs a novel photo-assisted electrochemical platform based on a GO/MoS 2 /TiO 2 ternary heterojunction, systematically characterized via XRD, TEM, FTIR, and XPS. Explicitly shifting the focus from conventional metric-chasing (e.g., pursuing extreme detection limits) to rational material design, this work thoroughly elucidates the structure–activity relationship and underlying synergistic mechanisms through comprehensive kinetic investigations (e.g., CV, EIS, and DPV). Experimental results demonstrate that the strategically designed cascaded band structure significantly boosts electrocatalytic activity and interfacial charge transfer. Furthermore, by leveraging the distinct structural advantages of the distinct structural advantages of GO/MoS 2 alongside the photo-assisted properties of TiO 2 , the sensor achieves a dual-mode “anti-fouling and self-cleaning” capability that effectively resolves surface fouling caused by oxidation products. Consequently, the sensor exhibits robust performance with a detection limit of 0.07 µM (S/N = 3) and three wide linear response ranges (7.865∼12.155 µM, 12.155∼71.5 µM and 71.5∼715 µM). Ultimately, this systematic study provides not only a robust platform for real-world APAP monitoring but also a theoretical blueprint for designing next-generation, passivation-resistant sensing interfaces. A photo-assisted GO/MoS 2 /TiO 2 ternary heterojunction sensor was constructed for ultrasensitive electrochemical detection of acetaminophen with enhanced charge transfer and excellent anti-fouling performance.(This graphical abstract was generated using AI tools) Download: Download high-res image (252KB) Download: Download full-size image

Probabilistic assessment of cumulative heavy metal exposure from staple foods in a selenium-endemic area: Implications for dietary risk management

Shixi Zhang,Yangchun Han,Kun Zheng,Yougen Zhong,Kunli Luo

While selenium (Se) exposure in endemic poisoning areas has been extensively investigated, its co-occurrence with other heavy metals and the implications for integrated environmental health management remain insufficiently addressed. This study developed a risk-based dietary optimization framework by assessing the concentrations, spatial distribution, and probabilistic health risks of 24 elements in four staple crops (rice, maize, potato, and sweet potato) collected from Shuang’an Township, a recognized human Se poisoning area in China. Results revealed widespread exceedances of maximum limits (ML) for Cd, Se, Cr, Zn, and Cu, with Cd (65.8% of samples exceeded ML; maximum exceedance factor = 145.7) and Se (52.1% exceeded ML; maximum exceedance factor = 56.3) posing the most significant risks. Potatoes exhibited the highest contamination levels among all crops. Monte Carlo simulations demonstrated that dietary composition substantially influenced cumulative health risks, with total target hazard quotient (TTHQ) values ranging from 9 to 24 under different consumption scenarios. Potato intake showed a significant positive correlation with TTHQ (r = 0.67, p < 0.05), whereas sweet potato intake showed a significant negative correlation (r = –0.71, p < 0.05), indicating sweet potato as a comparatively lower-risk alternative. The proposed probabilistic framework provides useful information for dietary risk management in Se-endemic areas. These findings highlight the necessity of shifting from a Se-centered management perspective toward integrated multi-metal risk control strategies in Se-endemic areas.

Hydrothermal-biogenic controls on critical metal enrichment in Ediacaran-early Cambrian stone coal of the Qinling-Daba Mountains

Shixi Zhang,Yangchun Han,Kun Zheng,Yichi Zhang,Litao Hao,Kunli Luo

Five correlatable stone coal layers formed in the Ediacaran-early Cambrian succession. • Critical metals display pronounced spatial-stratigraphic heterogeneity. • Layer 3 hosts anomalous Se-Mo and significant Cd-V enrichment. • Metal enrichment was dominated by hydrothermal fluids and enhanced by algal activity. • Ga, V, Mo, and Cd indicate substantial critical-metal resource potential. The Qinling-Daba Mountains represent one of the major stone coal bearing areas in China, where multiple stone-coal layers occur within the Ediacaran-early Cambrian strata. These stone coal are commonly enriched in critical metals; however, their spatial and stratigraphic enrichment patterns remain poorly understood. In this study, we investigated the enrichment characteristics of 14 critical metals across three major belts (southern, central, and north) in the Qinling-Daba stone coal area. The results show that the Ediacaran-early Cambrian strata contain five regionally correlatable stone coal layers, three within the Ediacaran and two within the lower Cambrian. Critical metal enrichment exhibits pronounced spatial and stratigraphic pattern: the southern belt displays the strongest enrichment, whereas layer 3 ( Z 2 3 Z23 ) consistently hosts the highest enrichment of critical metals. Within this layer, Se and Mo reach anomalous enrichment levels (EF max  > 100), and Cd and V are significantly enriched (EF max  > 10) across all three belts. Four critical metals, Ga, V, Mo, and Cd, show significant mining potential. Inorganic and organic geochemical evidence indicates that hydrothermal input was the primary control on metal enrichment across the five layers, whereas the exceptionally high metal enrichment in layer 3 were further amplified by biogenic contributions, particularly from marine algae. These findings clarify the spatial and stratigraphic controls on critical metal enrichment in the Qinling–Daba stone coal area and provide new insights into hydrothermal–biological interactions and metalliferous sedimentation in Ediacaran-Cambrian basins.

One-dimensional CdS nanorods with polydopamine shell for stable and efficient photocatalytic hydrogen peroxide generation

Wen Yang,Yun Lou,Zichen Liu,Yinze Yang,Zhuhe Zhai,Shengqiang Chen,Lili Zhang,Yafei Zhao,Bing Zhang

CdS@PDA was prepared by combining 1D CdS nanorods with PDA coating. • CdS@PDA displays exceptional H 2 O 2 production rates of 8564.24 and 7320.3 μmol g −1 h −1 under O 2 and air, respectively. • The synergistic interface accelerates charge separation and improve stability. • PDA promotes O 2 reduction via a two-electron pathway involving ·O 2 - radicals. Photocatalytic synthesis of hydrogen peroxide (H 2 O 2 ) from water and oxygen offers a sustainable alternative to the conventional anthraquinone process, but its efficiency is often limited by rapid charge recombination and photocorrosion of CdS photocatalysts. In this work, one-dimensional (1D) CdS nanorods coated with a polydopamine (PDA) shell were developed to improve photocatalytic H 2 O 2 production through synergistic morphological and interfacial engineering. The 1D CdS nanorods provide efficient charge transport pathways, while the PDA coating enhances light harvesting, improves interfacial charge separation, and suppresses photocorrosion. As a result, the optimized CdS@PDA-3 photocatalyst achieves H 2 O 2 production rates of 7320.3 μmol g −1 h −1 under air and 8564.2 μmol g −1 h −1 under O 2 , corresponding to an apparent quantum yield (AQY) of 35.8% at 420 nm, which are significantly higher than those of pristine CdS under identical conditions. Comprehensive structural, photoelectrochemical, and photocatalytic characterizations consistently indicate that PDA modification enhances interfacial charge utilization and catalyst stability. This work demonstrates an effective strategy for improving the activity and durability of CdS-based photocatalysts and provides useful guidance for the rational design of efficient photocatalysts for sustainable H 2 O 2 production.

Synergistic Ag single atoms and nanoclusters on defect-engineered In2S3 for enhanced H2O2 production and in-situ pollutant oxidation

Lingzheng Feng,Wei Han,Xiaojun Guo,Jianzhang Zhu,Jiaqi Shen,Xingguo Xiao,Hudong Yan,Fei Zha,Haifeng Tian,Xiaohua Tang

Nitrogen doping introduces sulfur vacancies and lattice distortion into In 2 S 3 , which enhances charge separation and provides anchoring sites for Ag species. • Achieves a high H 2 O 2 production rate of 965 μmol g −1 ·h −1 via the 2e − ORR pathway. • DFT reveals Ag single atoms optimize *OOH adsorption; clusters boost electron redistribution. • Exhibits efficient degradation of perphenazine (95% removal within 30 min). • Operates effectively in pure water without sacrificial agents and shows excellent stability. To address the rapid recombination of photogenerated charge carriers in indium sulfide (In 2 S 3 ) and meet the growing demand for efficient photocatalytic hydrogen peroxide (H 2 O 2 ) production systems, this study proposes a rational design. Leveraging active nitrogen species generated from urea decomposition during hydrothermal treatment, we successfully doped the In 2 S 3 lattice to construct a nitrogen-modified indium sulfide (N-In 2 S 3 ) substrate, and subsequently co-anchored silver single atoms and clusters (Ag SA+C /N-In 2 S 3 ) onto it for efficient photocatalytic H 2 O 2 production and pollutant degradation. Nitrogen (N) doping induced sulfur vacancies and lattice distortion, enhancing charge separation and surface reactivity. Ag species were atomically dispersed and firmly anchored onto the N-In 2 S 3 support, serving as efficient electron sinks and active sites. The optimized Ag SA+C /N-In 2 S 3 achieved a remarkable H 2 O 2 production rate of 965 μmol g −1  h −1 in pure water via a predominant two-electron oxygen reduction reaction (2e − ORR) pathway, significantly outperforming pristine In 2 S 3 and N-In 2 S 3 . Combined with experimental characterization and DFT calculations revealed that Ag single atoms optimized the adsorption of the *OOH intermediate and reduced the reaction free energy barrier, while Ag clusters facilitated electron redistribution and enhanced oxygen activation. It also demonstrated superior photocatalytic degradation efficiency for organic pollutant like perphenazine (95% removal in 30 min). This study highlights the synergistic effect of bulk doping and surface atomic-level engineering in developing high-performance photocatalysts for sustainable chemical synthesis and environmental remediation.

Analyte-Specific “Signal-On” Uranyl Sensitive Sensing Based on Temperature-Programmed Nanozyme Activity of CoOx

Bu Zhijian,Wang Linjie,Yao Yuxuan,Chen Xinyu,Tang Zheng,Du Dan,Wu Shengtao,Lin Yuehe,Liang Hao,Niu Xiangheng

As alternatives to bioenzymes, nanozymes find promising applications in biochemical sensing thanks to their recognized superiorities, but their lack of specific interactions with targets of interest seriously hinders the exploration of selective analytical strategies when no external receptors are employed. Additionally, most nanozymes exhibit poor catalytic efficiency, much lower than their natural counterparts, thus restricting the sensitivity of detection. Different from the explored “turn-off” analytical principle relying on the coordination of the target with a nanozyme catalytic product, here we proposed an analyte-unique “signal-on” strategy based on the direct target–nanozyme interaction for the sensitive sensing of uranyl via temperature-programming the peroxidase (POD)-mimetic activity of CoO x . As wet-chemical temperature increased, the oxygen vacancy (O V ) content on CoO x surfaces exhibited a volcano-type trend, and its catalytic efficiency correlated with the former positively. UO 2 2+ was found to stimulate the POD-like activity of CoO x via increasing O V , exhibiting excellent specificity against other common species. Leveraging the unique CoO x –UO 2 2+ interaction and the temperature-programmed activity of CoO x , we validated a “light-up” colorimetric approach for UO 2 2+ selective determination, achieving a wide detection range (0.01–2 μM) and a low limit (5 nM). A deployable device based on intelligent reading was further fabricated to enable on-site monitoring of the analyte. Our work provides a “signal-on” nanozyme sensing strategy for the quantification of UO 2 2+ , featuring specific response, catalytic signal amplification, and free from bioreceptors. Also, it proves a facile route to achieve dual modulation of enzyme-mimetic activity and analyte response for broader applications.

Atomic-to-Nanoscale Engineering of Piezocatalytic Heterojunctions for Ultrasound-Triggered Osteomyelitis Therapy

Lijing Chen,Chaofeng Wang,Shuilin Wu,Congyang Mao,Yuan Li,Cuihong Chen,Talante Juma,Yongping Cao,Yu Wang,Xiangmei Liu

Osteomyelitis, primarily caused by methicillin-resistant Staphylococcus aureus (MRSA), poses critical clinical challenges, including drug-resistant infections and insufficient bone regeneration. Herein, we propose a mechano-electro-chemical energy conversion paradigm based on an atomic-to-nanoscale synergistic strategy, realized by constructing a heterojunction between sulfur-doped zinc oxide and bismuth ferrite (S-ZnO/BiFeO 3 ). At the atomic level, sulfur doping induces lattice distortion and oxygen vacancies, narrowing the bandgap of ZnO. At the nanoscale level, sulfur doping modulates crystal growth, transforming ZnO nanoblocks into thinner nanosheets that establish intimate interfacial coupling with BiFeO 3 . This dual-scale synergy amplifies the piezoelectric coefficient (d 33 ) tenfold, significantly enhancing the ultrasound (US)-responsive piezocatalytic output. Under US, the enhanced piezocatalytic field facilitates directional charge migration and continuous reactive oxygen species (ROS) generation, achieving a 99.45% antibacterial rate against MRSA while effectively inhibiting biofilm growth. Transcriptomic profiling reveals that this energy conversion process eliminates MRSA via a multi-target collapse of membrane defense, ion homeostasis, and energy metabolism. Concurrently, S-ZnO/BiFeO 3 promotes osteogenic differentiation through US-triggered microcurrents and Zn 2+ release. In vivo results validated robust bactericidal potency, osseointegrative kinetics, and excellent biocompatibility. This study establishes a mechano-electro-chemical energy conversion paradigm via atomic-to-nanoscale engineering, offering a high-performance platform for precise piezocatalytic therapy.
