CsPbI 3 /Pt-g-C 3 N 4 Z-scheme heterojunction was created for efficient charge carrier separation. • 1D/2D heterostructure enhances interfacial contact and charge separation. • Pt nanocrystals act as electron mediators guiding directional charge flow. • Coupling photocatalysis with persulfate activation boosts degradation efficiency. • Singlet oxygen identified as the dominant reactive species in the system. A novel Z-scheme photocatalytic system was constructed by bridging graphitic carbon nitride (g-C 3 N 4 ) nanosheets with CsPbI 3 nanowires (NWs) via Pt nanocrystals (NCs) mediators. Comprehensive material characterization verifies that the rational combination of CsPbI 3 NWs and g-C 3 N 4 nanosheets leads to a well-defined 1D/2D heterostructure with intimate interfacial contact. Notably, Pt NCs as highly efficient electron mediators successfully establish a Z-scheme charge transfer pathway and thereby remarkably enhance the separation and migration efficiency of photogenerated carriers. Photoelectrochemical measurement confirms that g-C 3 N 4 /Pt/CsPbI 3 NW composites exhibit substantially elevated photocurrent density and remarkably reduced charge transfer resistance compared with the composites created using CsPbI 3 NCs, indicating the important role of 1D NW structure. Because of well-developed heterostructure and expanding visible light absorption, g-C 3 N 4 /Pt/CsPbI 3 NW composites revealed a degradation efficiency of 71.3% for 2,4-dichlorophenol while that of g-C 3 N 4 /Pt/CsPbI 3 NC composites is 62.9%. The degradation efficiency was further elevated to 82.8% with the introduction of persulfate, forming a coupled photocatalysis advanced oxidation process. Mechanistic studies demonstrate that the construction of Z-scheme heterojunction remarkably enhances the generation of superoxide radicals (·O 2 - ), with a resulting concentration of 12.23 × 10 –7 mol/L. These ·O 2 - species are subsequently converted into singlet oxygen, the primary active agent that works together with ·O 2 - and other radicals to synergistically degrade organic pollutants. These resultssuggest that a highly efficient and stable Z-scheme photocatalyst was created and offer important theoretical and practical guidance for advanced photocatalyst design.

The photocatalytic conversion of biomass-derived monosaccharides to lactic acid (LA) provides a sustainable approach for the high-value utilization of biomass. However, conventional photocatalysts suffer from insufficient visible light absorption, rapid recombination of photogenerated charge carriers, and inadequate surface active sites, which severely hinder the generation of key active species, thereby limiting the catalytic activity and LA selectivity. Herein, this study constructs a Z-scheme heterojunction photocatalyst TiO 2 /C-CN by combining carbon skeleton and oxygen vacancy (V O )–modified TiO 2 with graphitic carbon nitride (CN), with excellent photocatalytic performance. Under visible light irradiation, it achieves 92.3% LA yield and 96.4% selectivity within 60 min. The carbon skeleton effectively enhances visible light absorption and electron transport, V O provides abundant active sites for the adsorption and activation of oxygen, and the construction of the Z-scheme heterojunction achieves efficient charge separation while retaining strong redox capability. The synergistic effect of these three components facilitates the efficient generation of superoxide radicals ( ), which selectively cleave the C3 C4 bond of glucose intermediates, directing the reaction toward LA formation. This study provides a rational strategy to design efficient and precise photocatalysts for biomass valorization through the synergistic regulation of electron transport channels, defect sites, and heterojunction engineering.

The superior photoreduction of U(VI) under visible light irradiation is one of most attractive way for the sustainable development of nuclear energy, whereas the development of long-term stable, highly photocatalytic performance and low cost photocatalyst remains a challenge owing to the lack of accessible adsorption intensity in the visible light range. Herein, a boron-incorporated triazine-linked 2D covalent organic frameworks with amidoximeylation (B/AO-COF) was fabricated via solvent modulation method. In comparison with COF (0.0049 /min) and AO-COF(0.0102 /min), the large removal rate of B/AO-COF (0.0145 /min) showed the introduction of AO groups accelerated U(VI) removal. The high photocatalytic efficiency (~ 95 % within 1 h) and good stability (< 5 % after 5 recycles) of B/AO-COF under visible light irradiation was attributed to low recombination of photogenerated electron-hole pairs. According to quenching experiments and ESR analysis, photogenerated electrons and superoxide radials played an important role in U(VI) photoreduction. These findings are crucial for the application of B/AO-COF on the highly efficient removal of U(VI) from aqueous solution in actual environmental remediation.

Ensuring food safety requires reliable methods to monitor toxic contaminants like p-aminophenol (p-AP), which can migrate from plastic packaging or accumulate as veterinary drug residues in food products. However, the absence of rapid and field-deployable detection methods poses a persistent obstacle to its effective monitoring. In this work, we developed iron-doped silicon quantum dots (Fe-SiQDs) as a robust peroxidase-mimicking nanozyme and engineered a dual-mode sensing platform for p-AP detection comprising a solution-based assay for laboratory use and a hydrogel strip for on-site smartphone-assisted quantification. The solution assay achieved high sensitivity (LOD: 5.22 μM) with excellent correlation to HPLC (R² = 0.9994), while the hydrogel strip enabled quantification within 15 min without complex instrumentation. The Fe-SiQDs-based hydrogel sensor was tested on real-world food matrices including honey and bottled water, achieving accurate recoveries between 93.2% and 119.5% with high reproducibility (RSD < 2.1%). This cost-effective and field-ready system provides a practical solution for rapid screening of p-AP in food samples, offering a useful tool for food safety monitoring.

Within fuel cell systems, the proton exchange membrane (PEM) is an indispensable functional component; therefore, the design and development of PEMs with good mechanical strength and high energy density are essential for the efficient use of energy. In this work, the PIL-SGO filler was prepared and was introduced into the C-SPAEKS polymer matrix to prepare the composite PEMs. The C-S/PIL-SGO-1% membrane had a good comprehensive performance; among them, the tensile strength was 54.61 MPa. The proton conductivity reached the highest with 213.5 mS cm–1 (at 90 °C, 100% RH). The peak power reached 927.33 mW/cm2, and the OCV was 0.9626 V. The results showed that the introduction of functionalized graphene oxide effectively improved the comprehensive performance of PEMs.

Photocatalysis and piezocatalysis rely on light energy and mechanical energy (via the piezoelectric effect) as driving forces, respectively. Both have been successfully applied to pollutant degradation and wastewater treatment as advanced oxidation processes. However, in this study, BiFeO3 nanoparticles derived from MIL-101 were solidified in a flexible polyvinylidene fluoride (PVDF) porous structure, forming a dynamic synergistic effect between the piezoelectrically polarized electric field induced by mechanical agitation and the photogenerated carriers. Additionally, the hydrolytic inactivation of the material was inhibited by the chemical barrier effect of PVDF, while the charge separation at the heterojunction interface was directionally driven by the built-in electric field generated by the piezoelectric effect. The BiFeO3/PVDF composite membrane degraded 97.1% of RhB after 60 min of treatment under the synergistic effect of stirring and light. Free radical trapping and electron spin resonance (ESR) analysis confirmed that •O2– and •OH were the key active species (contributing over 60%). Piezoresponse Force Microscopy (PFM) test revealed the mechanism behind the enhancement of the built-in electric field, and density functional theory (DFT) calculations combined with Fukui’s function elucidated that the N4, N5, and C6 sites in the RhB molecule were the preferred targets for free radical attack. Plant growth experiments verified the environmental safety of the system. The BiFeO3/PVDF porous composites with piezoelectric photocatalytic properties proposed in this study provide a promising solution for developing novel materials for efficient catalysis of organic pollutants in water.

Bimetallic Ru-Co nanofibers (NFs) are successfully fabricated via an electrospinning technique coupled with thermal calcination and hydrogen reduction treatment. The optimized fibrous Ru 3 -Co 7 nanozyme demonstrates exceptional peroxidase (POD)-like activity, capable of oxidizing the chromogenic substrate 3,3′,5,5′-tetramethylbenzidine (TMB) by hydrogen peroxide (H 2 O 2 ) to generate oxidized TMB (oxTMB), yielding a characteristic blue response. Capitalizing on the ascorbic acid (AA)-mediated chromogenic attenuation mechanism via oxTMB reduction, a colorimetric sensing platform is established by tracking the absorbance variations at 650 nm. This AA quantification strategy achieves superior analytical performance, featuring a detection limit (LOD) of 0.87 μM, a broad linear response spanning 1–40 μM (R 2 = 0.993), and remarkable selectivity against interfering species. Furthermore, this platform is successfully applied to assess total antioxidant capacity in real-world samples, including fresh fruit juices and available beverage. The POD-like catalytic reliability is validated through parallel validation against the established cupric reducing antioxidant capacity (CUPRAC) assay, confirming the robustness of this strategy for practical antioxidant analysis.

The establishment of artificial photosynthetic systems for hydrogen peroxide (H 2 O 2 ) synthesis signifies a sustainable and eco-friendly strategy that could replace the conventional anthraquinone oxidation pathway. However, the majority of works have predominantly focused on the modulation of individual catalytic site, while systems that enable mutual regulation between adjacent catalytic sites have received little attention. Herein, we designed two novel ether-linked covalent organic frameworks (TpO-COF and TpOO-COF). Compared with TpO-COF, the cooperative interaction between adjacent oxygen catalytic sites in TpOO-COF results in a synergistic enhancement, yielding superior catalytic efficiency beyond the sum of isolated effects. When using benzoic alcohol as the sacrificial agent, a remarkable H 2 O 2 generation rate of 3067 μmol g −1 h −1 , the TpOO-COF catalyst demonstrates a 7.6-fold increase in activity compared to TpO-COF. According to theoretical analyses, TpOO-COF possesses considerably lower Gibbs free energies for the oxygen intermediates than TpO-COF, confirming the presence of mutual electronic modulation among its oxygen catalytic sites. This work advances a distinctive strategy for modulating catalytic sites while providing valuable mechanistic insights into the structure–activity interplay underlying H 2 O 2 formation.

Tetracycline (TC), as a persistent and widely detected antibiotic pollutant, poses severe ecotoxicological risks and necessitates rapid and efficient degradation strategies. Here, we demonstrate a photocatalytic self-Fenton process in which H 2 O 2 produced via visible-light-driven oxygen reduction is directly activated by Fe species for the rapid degradation of TC. To enable efficient H 2 O 2 production, a ternary ZnIn 2 S 4 / CdIn 2 S 4 /MnIn 2 S 4 (denoted as ZC 0.3 M 0.05 ) heterojunction photocatalyst was rationally constructed via a one-pot hydrothermal method. Structural analyses reveal that the three sulfides form a tightly coupled, multi-interfacial nanoscale architecture that induces pronounced interfacial strain and charge polarisation. Consequently, ZC 0.3 M 0.05 delivers a high H 2 O 2 production rate of 4907.7 μmol g⁻ 1 h⁻ 1 , outperforming pristine ZnIn 2 S 4 , CdIn 2 S 4 and MnIn 2 S 4 by factors of 15.2, 10.7 and 13.6, respectively. Upon Fe addition, the in situ generated H 2 O 2 enabled rapid self-Fenton degradation of TC, achieving 91.9 % removal within 5 min, while maintaining high activity under simulated environmental conditions. Combined spectroscopic, electrochemical and theoretical analyses reveal that work-function-difference-driven and stepwise electron-transfer pathways (MnIn 2 S 4 → ZnIn 2 S 4 → CdIn 2 S 4 ) across multiple heterointerfaces facilitate efficient charge separation and O 2 -to-*O 2 ⁻ electron injection. This work establishes a materials framework for on-demand H 2 O 2 production and direct self-Fenton pollutant remediation, and offers general design principles for high-performance ternary metal sulfide heterojunctions.

Efficient uranium extraction from wastewater is crucial for environmental protection and the sustainability of nuclear energy. Herein, we propose a novel uranium extraction strategy by integrating piezocatalysis and defect engineering, and elucidate the underlying interfacial mechanism. Oxygen-vacancy-rich ZnO (ZnO-OV) exhibits a 53% enhanced piezoelectric response, boosting U(Ⅵ) extraction efficiency by ∼34%with a high uranium uptake capacity of 904.17 mg g −1 . It also shows excellent durability, with only ∼0.7% efficiency loss after five adsorption–desorption cycles. Mechanistically, the superior performance of ZnO-OV arises from synergistic effects: oxygen vacancies facilitate polarization-induced charge separation and transfer, and provide abundant active sites for oxygen adsorption. Under ultrasonic stimulation, piezoelectric electrons from ZnO-OV directly reduce adsorbed UO 2 2+ species, trigger oxygen reduction and water oxidation to in situ generate H 2 O 2 , which reacts with UO 2 2+ and reduced UO 2 to form insoluble (UO 2 )O 2 ·2H 2 O for efficient uranium separation. This study reveals oxygen vacancies as pivotal active sites for oxygen adsorption and plays a determinant role in boosting piezocatalysis, offering fundamental insights into the rational design of defect-regulated piezocatalysts to promote interfacial redox reactions.

Addressing water scarcity and pollution in underdeveloped regions requires safe water production from inferior sources. Solar-driven interfacial evaporation (SDIE) coupled with photocatalysis offers great potential for this challenge. Herein, a dual-functional composite (BTG@MS) was fabricated by immobilizing oxygen vacancy- and Ti(III)-rich black TiO 2 /defective g-C 3 N 4 (BTG) on melamine sponge (MS) hydrogel. The composite broadens light absorption to 300–1200 nm (80.7% average absorption efficiency) and forms a type-II heterojunction, facilitating charge separation and reactive oxygen species (ROS) generation. Benefiting from MS’s hierarchical water transport pathways and BTG’s enhanced solar utilization, BTG@MS exhibits outstanding dual performance under one-sun illumination (1 kW/m 2 ), an evaporation rate of 1.26 kg/(m 2 ·h) (74.3% photothermal efficiency) and 84.5% tylosin (TYL) degradation efficiency. It also shows salt tolerance and effectiveness in purifying four types of water sources, producing clean water meeting WHO standards. This work presents an innovative strategy integrating photothermal evaporation and photocatalysis, promising practical application in tackling the water crisis in underdeveloped regions.

Enhancing interfacial carrier separation and overcoming the structural recalcitrance of raw biomass are major challenges in its direct photorefining for solar fuel and platform chemical production. Here, we report a rational interfacial microenvironmental modulation strategy to construct twin charge channels in ZnS(en)/CdS photocatalysts for efficient biomass valorization. Specifically, sulfur vacancies function as electron transport pathways, while surface-coordinated ethylenediamine molecules act as hole channels, synergistically promoting interfacial charge separation and transfer. These dual channels not only facilitate carrier utilization but also activate the biomass substrate, significantly boosting photocatalytic performance. As a result, the ZnS(en)/CdS system achieves an exceptional hydrogen evolution rate of 8.89 mmol g−1 h−1 and an organic acid production rate of 5.48 mmol g−1 h−1, both surpassing those of most previously reported photocatalysts. This work offers valuable insights into catalyst interface engineering and provides a robust strategy for advancing sustainable raw biomass photorefining.
