Ferroptosis, driven by redox imbalance, plays a critical role in osteoarthritis (OA) progression. Although antioxidant nanozymes hold therapeutic potential, designing highly efficient and targeted systems to inhibit ferroptosis remains challenging. Here, we developed a 2D nitrogen-doped graphene-like nanomesh (NGM) loaded with asymmetric and highly exposed Fe single atoms, carried with the cartilage-targeting WYRGRL peptide and siRNA (siMMP13) to form Fe SAzymes (si-FeSA/NGM-W) as ferroptosis inhibitors to alleviate OA. By mixed molten salt and Zn removal, exfoliating Zn-ZIF into an ultrathin 2D hierarchical porous NGM with topological defects and hierarchical structure, we created a scaffold for anchoring asymmetric and highly exposed Fe single atoms. The abundant Fe-N 4 -Cl coordination active sites then introduce strain and defects, which facilitate electron transfer, enhance radical adsorption, and lower reaction barriers, thereby augmenting multi-enzyme (SOD/CAT/GPx) activities. This enables the functionalized si-FeSA/NGM-W to target cartilage, where it inhibits ferroptosis by downregulating MMP13, upregulating GPX4, restoring mitochondrial function, and modulating inflammation, ultimately achieving targeted OA therapy. Mechanistically, this process involves suppression of the IL-17 pathway and enhancement of glutathione metabolism. This work presents a targeted nanozyme platform for precise OA therapy via ferroptosis inhibition.

Construct TiO 2 @MIL-101-Fe S-scheme via impregnation in situ hydrolysis. • Hierarchically distributed TiO 2 maximizes interfacial contact. • Achieves 13.91% cyclohexane conversion and retains high activity after five cycles. • Interfacial fields drive spatial charge separation and preserve redox potentials. • Hierarchical confinement and pore-mouth anchoring enable selective C H activation. The selective photocatalytic oxidation of cyclohexane is a sustainable and environmentally friendly route for KA-oil production, yet it remains limited by low conversion, moderate selectivity, and inefficient charge utilization. This study employed an in-situ TBOT hydrolysis strategy to synthesize a TiO 2 @MIL-101-Fe S-scheme heterojunction with hierarchically distributed TiO 2 nanodomains within the MOF pores, at pore mouths, and on the external surface. This spatially engineered heterostructure enhances photogenerated carrier separation, stabilizes the interface, and improves cyclohexane oxidation efficiency and KA-oil selectivity. The optimized 50 wt% composite material achieved a cyclohexane conversion rate of 14.3%, which was 2.17 times that of the original MIL-101-Fe material. Meanwhile, it still maintained a cyclohexane conversion rate of up to 13.9% and excellent catalytic activity after five cycles. Steady-state and time-resolved photoluminescence, electrochemical impedance, and transient photocurrent measurements reveal accelerated charge separation and prolonged carrier lifetime, enabled by an S-scheme heterojunction with a built-in interfacial electric field. Radical trapping and ESR studies indicate that photogenerated holes and electrons dominate C H activation, with reactive oxygen species contributing synergistically. DFT calculations confirm directional electron transfer and preserved high redox potentials. This work highlights spatially confined S-scheme heterojunctions as a general strategy to enhance photocatalytic efficiency, selectivity, and stability, offering a promising avenue for solar-driven hydrocarbon oxidation.

Energetic molecular perovskite (H 2 dabco)[NH 4 (ClO4) 3 ] (DAP-4) had attracted much attention due to their strong oxidizing ability and high energy characteristics. However, the high thermal decomposition temperature would affect their potential application in the fields of propellants. In this work, Fe-doped carbon (Fe-Carbon) composites were prepared by a simple and facile high-temperature carbonization method with the iron salt-contained biomass flour materials as carbonized porous precursor. And the influence of Fe-Carbon composites on catalytic thermal decomposition and combustion on DAP-4 was studied. The results showed that porous Fe-Carbon composites with the low contents of Fe x O y showed the intrinsic catalyzed decomposition properties towards DAP-4. With the adding of 5wt% Fe-Carbon-3, the thermal decomposition temperature of DAP-4 had reduced by 25 °C from 374 °C (DAP-4) to 349 °C (DAP-4/Fe-Carbon-3). The apparent activation energy of thermal decomposition of DAP-4 had reduced by 16.25 kJ·mol -1 with the appearance of Fe-Carbon-2. DAP-4/Fe-Carbon-3 had a shorter combustion process (∼80 s) than DAP-4 (∼110 s). The maximum combustion temperature and combustion heat had increased. The catalysis thermal decomposition and combustion mechanism of DAP-4 with Fe-Carbon was provided. Fe x O y with high dispersion at the surface of carbon materials enhanced hydrogen transfer from ammonium and protonated H 2 dabco 2+ cations to perchlorate anions, which accelerated decomposition and combustion reaction of DAP-4. This work showed a novel understand of catalysis decomposition and combustion reaction of energetic molecular perovskite by metal-doped carbonization materials.

Warp sizing and desizing are the indispensable process for high-speed and smart weaving. Biodegradable and low-cost soy protein (SP) exhibits easy film formation and is a promising candidate for use as textile sizing agent. However, current sizing agents confront the trade-off between strong yarn adhesion and easy desizing. In this work, ferrous ion (Fe (II)) was introduced as coordination bridges between SP size and yarns, inducing alterations in secondary structure of protein during sizing, thereby enhancing interfacial interactions through increased coordination and electrostatic adsorption. Compared to the original yarn, the adhesion between SP size and Fe (II) modified yarn increased by 21.78%, promoting an increase in the strength and abrasion resistance of sized yarn by 11.96% and 24.96%, respectively. High-efficiency desizing was achieved through chelation of Fe (II) with ethylenediaminetetraacetic acid (EDTA). A 97.89% desizing efficiency and 93.52% removal of surface Fe (II) were rapidly arrived under treatment in 0.1 M EDTA at 60 °C, representing increases of 32.27% and 80.19%, respectively, over water desizing. Modified SP sizing system mainly via Fe (II) coordination enable controllable high efficiency of sizing and desizing simultaneously, provides a promising approach for the development of yarn coating and sustainable textile industry.

Diacetyl (2,3-butanedione) is an important ingredient used in the food and perfume industries, whose synthesis is largely constrained by environmental pollution and low selectivity. In this study, Fe-MIL-88B_NH2 has been successfully synthesized via the microwave-assisted solvothermal method, which exhibits high reactivity in acetoin oxidation, affording 81.3% conversion and 95.8% selectivity toward diacetyl under mild conditions in the presence of NHPI (N-hydroxyphthalimide). Raman and a series of characterizations reveal that O2 is activated by surface Fe(II) on Fe-MIL-88B_NH2 with the generation of ≡Fe-OO• superoxo, which then abstracts H from acetoin with the formation of diacetyl and H2O2. Quenching experiments indicate that ≡Fe-OO• superoxo on Fe-MIL-88B_NH2 is the primary oxidizing species in the oxidation of acetoin. EPR and DPD analyses further reveal that the NHPI/PINO cycle effectively shuttles H from the acetoin to ≡Fe-OO• superoxo, thus enhancing the oxidation efficiency of acetoin. This study enriches our understanding on the importance of surface superoxo species and the H-shuttle in the selective oxidation of alcohols toward ketones.

Against the background of carbon peaking and carbon neutrality goals, green hydrogen has become a clean and efficient energy carrier and a core driving force for energy transition. Water electrolysis accounts for 90% of green hydrogen production and serves as the key route for green hydrogen preparation. However, performance bottlenecks of conventional catalysts severely restrict the large-scale application of green hydrogen. High-entropy alloys, with their unique cocktail effect and lattice distortion, offer an approach to overcome this challenge and have emerged as a critical breakthrough in the green hydrogen field. This work systematically investigated the effect of vanadium content on the electrocatalytic performance of Fe 40− x (CoCrNiMn) 60 V x high-entropy alloys, focusing on the optimization of hydrogen evolution reaction (HER) activity, and aimed to develop non-noble metal bifunctional electrocatalysts suitable for both freshwater and seawater working conditions. The results showed that the Fe 39 (CoCrNiMn) 60 V 1 alloy exhibited excellent HER performance within the same system in 1 M KOH electrolyte at a current density of −10 mA cm −2 , with an HER overpotential of only 98.3 mV, which was superior to that of most non-noble metal catalysts. This alloy also delivered favorable oxygen evolution reaction (OER) activity with an OER overpotential of 291.7 mV, and no obvious performance decay occurred after a 30 h stability test. In alkaline seawater electrolyte, the alloy maintained stable HER activity, with the HER overpotential slightly increasing to 106.2 mV at an equivalent current density, and the OER overpotential reached 350 mV. In overall water splitting tests, the Fe 39 (CoCrNiMn) 60 V 1 alloy retained outstanding performance after 100 h of testing in both alkaline freshwater and alkaline seawater electrolytes, which fully demonstrated its great potential to replace noble metal catalysts and realize efficient hydrogen production from seawater. This work not only provided insights into the design of high-entropy alloy electrocatalysts but also was of great significance for enhancing HER performance, promoting large-scale green hydrogen production, and achieving efficient utilization of seawater resources.

NH₂-MIL(Fe) is grafted onto amino-functionalized NH₂-PS resin to gain micro-nanoscale adsorbent. • SMX adsorption is favorable at pH 5.2–8.0 with an adsorption capacity of 250.61 mg·g −1 . • Hydrogen bonding and electrostatic attraction are the driving forces for SMX adsorption. • The Fe(III) centers in MOF endow NH₂-PS@NH₂-MIL(Fe) Fenton-like catalytic activity. Sulfonamide antibiotics (SAs) are ubiquitous in the aquatic environment and difficult to remove using conventional wastewater treatment processes. Adsorption and Fenton-like oxidation are efficient techniques for the elimination of SAs from water. In this study, a novel hierarchical micro-nano structural adsorbent was synthesized by grafting Fe-based MOFs (NH 2 -MIL(Fe)) onto amino-functionalized polystyrene-divinylbenzene resin (NH 2 -PS). The physicochemical properties and structural features of the composite (NH 2 -PS@NH 2 -MIL(Fe)) were systematically characterized by SEM, EDS, XRD, FTIR, BET and XPS, confirming the successful immobilization of NH 2 -MIL(Fe) on the PS surface and the presence of abundant active sites. The adsorption behavior of sulfamethoxazole (SMX) on NH 2 -PS@NH 2 -MIL(Fe) was evaluated under various conditions, including pH, adsorbent dosage, and coexisting anions. The adsorption process followed the pseudo-second-order kinetic model and Langmuir isotherm model, indicating a monolayer sorption with a maximum capacity of 250.6 mg·g −1 at pH 5.2 and thermodynamic analyses revealed that the adsorption was spontaneous and exothermic. Based on FTIR, XRD and XPS analyses, electrostatic attraction, hydrogen bonding, π–π stacking, and metal–ligand coordination/Lewis acid-base interaction collectively governed the adsorption of SMX. Furthermore, the Fe(III) centers endowed NH 2 -PS@NH 2 -MIL(Fe) Fenton-like catalytic activity. With the addition of H 2 O 2 , over 95% of SMX was eliminated rapidly from water in a wide pH range. Based on the dual functions, this material can efficiently remove SMX from surface water samples. These results highlight the great potential of NH 2 -PS@NH 2 -MIL(Fe) for efficient removal of sulfonamide antibiotics. Download: Download high-res image (319KB) Download: Download full-size image

A dual-channel electron-donation pathway enables reductant-free Fe 2+ /Co 2+ regeneration. • Pollutants and S 2- synergistically drive reversible M(III)/M(II) redox cycling. • Co 9 S 8 /FeS/PMS achieves rapid and complete levofloxacin degradation within 10 min. A magnetic Co 9 S 8 /FeS composite derived from cobalt slag was developed for reductant-free PMS activation through a novel dual-channel electron-donation pathway involving S 2- species and levofloxacin (LEV). The catalytic performance and mechanism were investigated through degradation kinetics, reactive-species identification, X-ray absorption fine spectroscopy (XAFS), X-ray photoelectron spectroscopy (XPS) analyses, density functional theory (DFT) and life cycle assessment. The Co 9 S 8 /FeS/PMS system completely degraded LEV within 10 min (k = 0.4498 min −1 ), maintained efficient removal over pH 3.0–11.0 and after five cycles (>95%), with 1 O 2 as the dominant reactive species. DFT calculations, together with XAFS/XPS analyses, revealed that S 2− and LEV serve as dual electron donors to facilitate Fe 3+ /Co 3+ reduction, achieving nearly complete Fe/Co redox cycling and sustained PMS activation. Compared with conventional single-electron-donor Fenton-like systems, this strategy eliminates the need for external reductants and substantially reduces environmental impacts, offering a sustainable route for converting cobalt slag into recyclable catalysts for antibiotic wastewater treatment.

The Fe–Cu–Mn based layered oxides have gained considerable attention as particularly promising cathode materials for sodium-ion batteries (SIBs) due to their low cost, earth abundance, and favorable electrochemical properties. However, current research often treats this system as a unified matrix, which obscures the specific contributions of the individual Fe, Cu, and Mn components in determining structural stability and electrochemical performance. Herein, we systematically investigate the ternary Fe–Cu–Mn system without the addition of extraneous elements. By precisely tuning the stoichiometric ratios of Fe, Cu, and Mn within a Mn-rich layered framework, a direct correlation is established between composition, structure, and electrochemical behavior. It reveals that optimizing the Fe/Cu/Mn ratio effectively suppresses undesirable phase transitions, enhances structural stability, and results in superior electrochemical performance. The Na 0.70 Fe 0.15 Cu 0.15 Mn 0.70 O 2 (NFCM-0.70) cathode delivers a high initial energy density of 293.87 Wh kg −1 (based on the mass of the cathode) and presents the excellent capacity retention of 82.9% after 100 cycles at 0.2C. This work underscores the importance of rationally controlling intrinsic component ratios as a strategy for developing low-cost, high-performance layered oxide cathodes for SIBs.

Composted pig manure (CPM) contains abundant organic matter; however, its complex matrix tends to undergo competitive carbonization during pyrolysis, limiting humification efficiency. In this study, a two-step process combining Fe-assisted low-temperature pyrolysis with alkaline extraction was developed to convert CPM into potassium humate (HA-K). Under optimized conditions (225 °C, 120 min, 5 wt% KOH), the HA-K yield increased from 49.07% to 78.14% with the addition of 1.5 wt% Fe, indicating a substantial enhancement in conversion efficiency. Fe incorporation promoted oxygen functionalization, aromatic condensation, and molecular reorganization, resulting in more humified structures approaching natural humic substances. Mechanistically, Fe facilitated the redistribution of reactive intermediates during pyrolysis, favoring the formation of nitrogen-containing heterocycles and stable aromatic frameworks. Correspondingly, the obtained humic substances exhibited enhanced bioactivity, significantly promoting wheat growth. At the optimal concentration (100 mg/L), shoot and root lengths increased by 8.15% and 54.78%, respectively, accompanied by increased biomass accumulation and protein content. This work provides new insight into Fe-driven thermochemical humification and offers a scalable route for the high-value utilization of livestock waste.

Fe-based amorphous alloys have garnered significant attention as high-efficiency Fenton-like catalysts for wastewater treatment due to their unique disordered atomic structure and abundant active sites. However, challenges remain in achieving both ultra-fast degradation kinetics and facile catalyst recovery. In this study, magnetically recoverable Fe-Si-B amorphous nanoparticle catalysts were successfully prepared by the chemical reduction method, and Rhodamine B degradation experiments were carried out under a Fenton-like system. The structural, morphological, compositional, thermal, and magnetic properties of the Fe-Si-B nanoparticles were characterized before and after the catalytic reaction. The results demonstrated that the nanoparticles retained their amorphous structure after the catalytic reaction and exhibited excellent soft magnetic properties with a saturation magnetization of 94.41 emu/g. Under conditions of 5 mM H 2 O 2 , 70 °C temperature, and pH = 3, the catalyst achieved over 99 % degradation efficiency for 20 mg/L Rhodamine B within 2 min at a dosage of only 10 mg/L. The degradation process followed a pseudo-first-order kinetic model with an activation energy as low as 37.62 kJ/mol. Radical quenching experiments indicated that ·OH played a dominant role in the degradation reaction, and the synergistic effect between the amorphous structure and high-density active sites significantly enhanced the generation efficiency of ·OH, thereby improving catalytic performance.

Modifying noble metal catalysts with transition metal oxides (MO x ) can markedly enhance catalytic performance through synergistic effects, yet precise spatial colocalization of active metal and promoter phases remains challenging. Here, we report the synthesis of KIT-6 supported Pd-MO x (M = Fe, Co, Ni) hybrid nanostructures via in situ transformation of bimetallic PdM nanoparticles under controlled thermal conditions. The resulting Pd-MO x /KIT-6 catalysts displayed superior activity and selectivity in the selective hydrogenation of acetophenone to 1-phenylethanol compared with monometallic Pd/KIT-6. Among them, Pd-CoO x /KIT-6 (Pd/Co=1:1) achieved the highest performance, with 99.7% acetophenone conversion and 98.2% selectivity, and demonstrated broad applicability for hydrogenating diverse ketones. Structural and kinetic studies revealed that interfacial Pd-CoO x sites play a pivotal role: Pd domains efficiently dissociate H 2 , while CoO x species enhance acetophenone adsorption. This synergistic interface-driven mechanism provides a general and costeffective strategy for the selective hydrogenation of multifunctional substrates.
