The lithium battery recycling industry is developing rapidly, and the rapid oxidation and degradation of dimethyl carbonate (DMC) in the wastewater generated by this industry is of crucial importance. In this study, Fe and Cu dopants were controlled and the C-SiO2framework with porous structures was constructed to synthesize FeCuC-SiO2and C-SiO2catalysts. The former could achieve 91.65% of DMC degradation within 60 min through peroxymonosulfate (PMS) activation, and the degradation rate was increased to 4.44 times compared to C-SiO2without Fe and Cu doping. And under optimized conditions, a DMC degradation rate of 90.57% can be achieved within 10 min by FeCuC-SiO2. The catalyst has good stability and the catalytic activity can be maintained during reuse process for five times with over 70% of DMC degradation rate, 58.9% of mineralization rate, and a relatively low amount of metal leaching. Moreover, the degradation rate can still remain above 70% with the existence of impurity anions, demonstrating a strong salt resistance. Hydroxyl radicals (OH•), sulfate radicals (SO4•−), and1O2were found to dominant the reaction in the FeCuC-SiO2-PMS system, which were involved in both free radical and non-free radical pathways and led to excellent catalytic oxidation performance and environmental adaptability. In general, a novel design for a Fenton-like catalyst was presented, providing a theoretical basis for the improvement of oxidation efficiency and the regulation of reaction pathways in Fenton-like reactions.

Lead (Pb) and cadmium (Cd) in soil threaten agroecosystem safety and human health. Due to the high bioavailability and mobility of heavy metals in red soil, the risk is further increased. Biochar is widely used for heavy metal immobilization, but original biochar suffers from inherent limitations. Most existing studies of iron (Fe)–manganese (Mn) modified biochar have not focused on red soil, and the relationship with soil–plant responses remains unclear. This study aimed to evaluate and compare the efficacy of sugarcane bagasse biochar (BC) and Fe–Mn modified sugarcane bagasse biochar (FMBC) for Pb and Cd immobilization in red soil, and clarify their effect on plant uptake. BC and FMBC were applied to Pb and Cd contaminated red soil for pot experiments with pak choi ( Brassica rapa chinensis ) as an indicator plant. The results showed that both BC and FMBC elevated soil pH, organic matter (SOM), enzyme activities, reduced Pb and Cd bioavailability, and transformed Pb and Cd to stable fractions. FMBC outperformed BC, and the 5% FMBC treatment achieved the optimal remediation efficacy. The 5% FMBC decreased the acid-extractable Pb and Cd by 9.33 and 34.40% compared to control. The plant biomass was significantly increased, Pb and Cd content in edible shoots met the limit standards, and bioconcentration (BCF) and translocation factors (TF) were lowered. Overall, this study establishes theoretical foundations and empirical bases for the application of FMBC to immobilize Pb and Cd in red soils, thereby providing a feasible and eco-friendly approach to support sustainable agriculture and the recycling of agricultural waste.

Sulfur dioxide (SO 2 ) has been recognized as the fourth gasotransmitter and holds great promise for antibacterial infection therapy. However, near-infrared (NIR) laser-triggered SO 2 -releasing nanoplatforms remain underdeveloped. Herein, a raspberry-like mesoporous Fe single atom nanozyme (Fe mSAz) with NIR-II laser-reinforced peroxidase (POD)-like activity was synthesized to construct a smart SO 2 -controlled release platform. To this end, the SO 2 donor 2,4-dinitrobenzenesulfonyl chloride (DN) was first loaded into the pores of Fe mSAz with the aid of a phase change material (PCM), followed by surface functionalization with a macrophage membrane (M), yielding a biomimetic SO 2 -releasing nanozyme denoted Fe mSAz@DN@M. Upon 1064 nm laser irradiation, the photothermal effect of Fe mSAz@DN@M first induced melting of the PCM to release DN, which subsequently triggered a burst of SO 2 generation. In the meantime, 1064 nm laser irradiation enhanced the POD-like activity of Fe mSAz by generating a substantial amount of hydroxyl radical (ꞏOH). As a result, Fe mSAz@DN@M exhibited robust antibacterial efficacy through a synergistic SO 2 /ꞏOH effect. Mechanistic studies revealed that SO 2 and ꞏOH synergistically suppressed bacterial activity by amplifying bacterial ferroptosis-like death. Furthermore, due to macrophage membrane functionalization, Fe mSAz@DN@M achieved highly effective targeting of subcutaneous tissues infected with Staphylococcus aureus ( S. aureus ) in mice. Consequently, Fe mSAz@DN@M also demonstrated excellent in vivo antibacterial infection efficacy through the synergistic SO 2 and ꞏOH effect, which not only eradicated the infectious bacteria but also subsequently induced repolarization of anti-inflammatory M2 macrophages to promote wound healing. A biomimetic SO 2 -releasing Fe single atom nanozyme (Fe mSAz@DN@M) was reported. NIR-II laser irradiation controls the simultaneous release of both ꞏOH and SO 2 , which synergistically boosted the antibacterial infection efficacy of the nanozyme by amplifying bacterial ferroptosis-like death.

As leading nonprecious metal electrocatalysts for ORR, Fe–N–C systems still face critical limitations. The insufficient density of accessible metal active sites and the intrinsic balance conflict between activity and durability largely constrain their practical application. In this study, we employed a coupled strategy of electrostatic assembly and defect confinement, followed by two-step high-temperature pyrolysis under distinct activation atmospheres. Cobalt clusters were in situ grown on the surface of carbon nanotubes to form a micro–nano anchoring structure with edge defects, enabling the simultaneous immobilization of Fe–N4 moieties and uniform dispersion of Co clusters on nitrogen-doped carbon nanotube substrates. The resulting nanotube-shaped Co@Fe/NC-a catalyst (prepared at 1100 °C with hydrogen activation) exhibited markedly improved ORR activity and stability in 0.1 M KOH compared with Fe/NC-a. X-ray absorption spectroscopy revealed that the Co clusters modulate the electron distribution at the Fe–N4 sites. Further, density functional theory (DFT) calculations confirmed that the Co clusters alter the electronic structure of Fe–N4 sites, reducing the reaction energy barrier and improving catalytic performance. Overall, this work offers a viable strategy for improving ORR catalysts by electronically tuning Fe–N4 sites through adjacent metal clusters.

Dual single-atom catalysts (DACs) represent a promising frontier in the field of electrocatalysis. However, the precise construction of DACs with modulated microenvironment to enhance oxygen electrocatalytic activities remains a formidable challenge. In present work, we report a chlorine-mediated strategy to manipulate the microenvironment of dual atomic iron sites, which are anchored on carbon nanocages with surface curvature (Fe-DSA-Cl/SCNC). Theoretical calculation results reveal that the chlorine atom modulates the local microenvironment of iron dual atom sites, decreases the energy barrier, and adjusts the oxygen adsorption/desorption capability, resulting in the enhanced electrocatalytic activities. Finite element analysis (FEA) modeling results demonstrate the hollow carbon nanocage with surface curvature regulates the local electric field, improves the mass transfer, and accelerates oxygen reaction kinetics. Benefitting from both aspects of advantages, the Fe-DSA-Cl/SCNC catalyst exhibits the excellent oxygen catalytic properties with a high half-wave (E 1/2 ) potential of 0.926 V in alkaline condition and a peak power density of 289 mW cm −2 in full Zn-air battery (ZABs). Furthermore, the quasi-solid-state Zn-air batteries operates smoothly over a wide range of temperature and achieves a high stability during long-term and low-temperature cycling. Therefore, this work gives a new insight into the local microenvironment modulation and spatial configuration engineering in dual atomic sites for enhanced catalytic properties. Moreover, it also gives a new clue to design and fabrication of oxygen electrocatalysts for different working conditions. Download: Download high-res image (107KB) Download: Download full-size image

Chlorophenolic contaminants represented by 2,4-dichlorophenol (2,4-DCP) are ubiquitous persistent and toxic organic pollutants in aqueous environments, posing severe threats to ecological safety and human health. Bimetallic zero-valent iron systems have emerged as promising candidates for the remediation of chlorinated wastewater; nevertheless, their practical application is greatly hindered by inevitable nanoparticle aggregation, poor dispersion, and insufficient exposure of active sites. To overcome these limitations, tannic acid (TA) with abundant phenolic hydroxyl groups was rationally grafted onto three-dimensional porous polyurethane foam (PU) to construct a novel composite support. Benefiting from the strong metal chelation of TA, Fe/Pd bimetallic nanoparticles were uniformly dispersed and firmly immobilized on the TA-PU skeleton, successfully fabricating the stable TA-PU-Fe/Pd catalytic composite. The catalytic performance toward 2,4-DCP degradation was systematically evaluated. Compared with conventional carriers such as activated carbon, zeolite and Al 2 O 3 , the as-prepared TA-PU-Fe/Pd exhibited remarkably enhanced removal activity, achieving a 2,4-DCP removal efficiency of 99.7% at an initial concentration of 20 mg/L. Moreover, the composite possessed outstanding cyclic reusability, retaining a high removal rate of 98.7% even after ten reaction cycles. Satisfactory treatment performance was also realized at a low pollutant level of 2 mg/L, with the removal efficiency reaching 93.0%, demonstrating great application potential for the remediation of actual chlorophenol-contaminated water.

Residual sulfamethoxazole (SMX) in aquatic environments poses risks to ecosystems and human health. Due to their exceptional mechanical strength and chemical durability, ceramic membranes (CMs) provide a suitable platform for heterogeneous catalytic oxidation. The synthesis of Fe 2 O 3 -CeO 2 @CM for catalyzing ozone oxidation to remove SMX was done in this study using a hydrothermal in-situ growth technique. The findings showed that when the Fe/Ce molar ratio was 1:3, the calcination temperature was 500°C, and the catalyst loading was 8.4 mg/g, the SMX was totally removed in 10 min in the presence of Fe 2 O 3 -CeO 2 @CM. The characterisation results showed that the material comprised FeCe solid solution and Fe 2 O 3 particles, exhibiting multiple valence states (Fe 2+ /Fe 3+ , Ce 3+ /Ce 4+ ). Based on the quenching experiments, ·OH, ·O 2 - , and 1 O 2 radicals were shown to be involved, with ·O 2 - and 1 O 2 playing primary roles. Mechanistically, the Fe 2+ /Fe 3+ and Ce 3+ /Ce 4+ species in the catalyst exhibited favourable redox cycling, promoting oxygen vacancy regeneration and serving as key active sites for catalysing O 3 decomposition. Furthermore, the system demonstrated excellent cycling stability, maintaining SMX removal rates above 95% after five cycles and achieving 94% removal in actual wastewater, effectively mitigating membrane fouling. An effective and reliable technique for eliminating antibiotics from wastewater is presented in this work.

To address the low Fe 3+ /Fe 2+ redox cycling efficiency of Fe-based catalysts during peroxymonosulfate (PMS) activation, this study successfully constructed a MIL-101(Fe)/WS 2 composite catalytic material. The results show that the MW 1:1 composite exhibits excellent performance toward PMS activation. By leveraging the cooperative effect of dual-metal cycling between Fe 3+ /Fe 2+ and W 4+ /W 6+ , as well as unsaturated sulfur vacancies, it achieves 97% phenol degradation within 60 min, with a reaction constant of 0.1038 min −1 , which is approximately 110 times that of single MIL-101(Fe) and WS 2 . The effects of key operating parameters such as catalyst dosage, PMS concentration, pH value and coexisting anions on phenol degradation efficiency were systematically evaluated. Through in-depth radical quenching experiments and electron spin resonance (ESR) spectroscopy analysis, it was clearly identified that sulfate radical ( SO 4 ∙ − ) and singlet oxygen ( 1 O 2 ) were the main active oxide species driving the degradation reaction. Furthermore, this study further elucidated the degradation means of phenol, proclaimed the reaction mechanisation, and evaluated the ecological toxicity of phenol and its intermediate products using the ECOSAR model. This work provides new insights for constructing efficient iron-based catalysts to activate PMS and promoting its application in the control of refractory organic pollutants.

Building upon a diagnostic assessment of nitrogen and phosphorus pollution in the Jingzhou Moat, this work developed a novel Fe-Mn oxide composite for the targeted removal of nitrate. An assessment of the water quality revealed a typical pattern of low phosphorus and high nitrogen pollution, with nitrate being the predominant contaminant. A novel Fe-Mn oxide modified activated carbon (FeMnAC) composite with a well-anchored MnFe 2 O 4 spinel structure was synthesized using a controlled activation, impregnation, and calcination procedure. The composite has an increased point of zero charge (pH 9.6), allowing for excellent nitrate adsorption throughout a wide pH range (2∼10). The adsorption process follows the Langmuir monolayer chemisorption model, with a maximum adsorption capacity of 23.19 mg·g −1 . FeMnAC demonstrated exceptional selectivity in the presence of competing anions like PO 4 3– while achieving highly efficient nitrate removal in real moat water samples in 120 min. After four regeneration cycles using NaCl, the adsorbent showed good reusability, retaining more than 50% of its initial capacity. This work offers a transferable methodological framework for nitrogen pollution control in similar heritage urban water systems by combining pollution diagnosis, targeted material design, and practical validation.

The escalating severity of global water scarcity and pollution necessitates the development of efficient and sustainable treatment technologies. Solar-driven interfacial evaporation presents an environmentally friendly, low-energy solution for both seawater desalination and wastewater treatment. In this study, we introduce a multifunctional integrated spherical evaporator composed of lignin-wrapped ZnFe 2 O 4 /chitosan‑carbon aerogel spheres (ZFO/CLCA), employing renewable chitosan as a three-dimensional flexible framework. By integrating ZnFe 2 O 4 , a visible-light-active semiconductor, with sodium lignosulfonate, known for its excellent photothermal conversion capabilities, we constructed a three-component organic hybrid featuring an in-situ formed hierarchical porous structure through a one-step carbonization process. The resulting ZFO/CLCA material demonstrates a high density of interconnected multiscale pores, a substantial specific surface area, and broad-spectrum absorption (93.48% across 250–2500 nm). Under simulated solar irradiation (1 kW m −2 ), this material exhibits an evaporation rate of 2.33 kg m −2 h −1 and a solar-to-steam conversion efficiency of 94.54%. The distinctive through-hole structure effectively prevents surface salt accumulation in high-salinity environments (3.5–20 wt% NaCl) via concentration-gradient-driven ion reverse diffusion, maintaining excellent long-term stability over 12 h of continuous operation. Importantly, during photothermal evaporation, the material concurrently catalyzes the degradation of organic pollutants, achieving an 87.10% degradation rate of tetracycline (100 mg L −1 ). In the context of real industrial wastewater treatment containing high salt concentrations and antibiotics, the evaporator produces clean effluent that complies with discharge standards. This study highlights a multifunctional spherical carbon aerogel evaporator that integrates efficient photothermal evaporation, salt resistance, and catalytic degradation, thereby, establishing a promising material platform for integrated solar-driven water treatment systems with both scientific significance and practical application potential.

Developing non-noble metal catalysts with both high activity and stability for the oxygen reduction reaction (ORR) remains a major challenge. Herein, we report a phosphorus-induced electronic coupling strategy to construct a dual-active-site catalyst composed of Fe single atoms and Fe2O3 nanoparticles anchored on a hierarchically porous carbon matrix derived from sugarcane bagasse biochar (Fe–P–C–Fe2O3/SBB). Phosphorus doping modulates the local coordination environment and facilitates the formation of Fe–P–O bonds, which bridge Fe single atoms and Fe2O3 nanoparticles, enabling interfacial charge redistribution. This electronic coupling optimizes the Fe d-band center, balances the adsorption strength of oxygen intermediates, and promotes a four-electron ORR pathway. As a result, the Fe–P–C–Fe2O3/SBB catalyst delivers a half-wave potential of 0.80 V (vs. RHE) and a Tafel slope of 75.6 mV dec−1, rivaling commercial Pt/C. Notably, the achieved ORR performance is comparable to or surpasses that of many recently reported non-noble metal catalysts, highlighting its strong potential for practical applications in fuel cells and metal–air batteries. Moreover, the catalyst exhibits remarkable durability and methanol tolerance. This work not only provides an atomically and electronically coupled Fe-based catalytic system but also offers a general strategy for designing sustainable biomass-derived dual-active-site catalysts through heteroatom-induced electronic coupling.

Therapeutic drug monitoring of isoniazid (INH), a first-line antitubercular agent, is critical due to its narrow therapeutic window and risk of toxicity or resistance at nonoptimal concentrations. Current methods lack the simplicity and accessibility required for point-of-care testing (POCT), especially in resource-limited settings. Herein, we report a paper-based colorimetric biosensing platform that integrates hollow-structured Fe-NC (Iron-Nitrogen-Carbon) nanozymes with smartphone-assisted readout for rapid, sensitive, and selective detection of INH in human biofluids. The nanozyme is synthesized via controlled pyrolysis of a dual-linker zeolitic imidazolate/tetrazolate framework (ZTF), where 2-methylimidazole (2-MIM) and thermally labile 5-aminotetrazole (5-AT) direct the formation of a hollow architecture that maximizes accessible Fe-N 4 active sites and enhances mass transport. This design confers superior peroxidase-like activity, enabling catalytic oxidation of chromogenic substrates in the presence of H 2 O 2 with high specificity toward INH. The resulting sensor achieves a detection limit of 0.24 μM and maintains high accuracy in human serum and urine, with minimal matrix interference. The entire assay is completed using a portable, low-cost device and a smartphone application for colorimetric analysis. Validated on human urine and serum, the platform demonstrates excellent reproducibility, stability, and field adaptability. This work presents a rational nanozyme design strategy through ligand-mediated structural control and establishes a scalable, equipment-free sensing framework for real-time therapeutic drug monitoring in POCT.
