Efficient and durable alkaline water electrolysis at industrial current densities remains a key challenge due to sluggish oxygen evolution kinetics and poor stability of hydrogen evolution reaction (HER) catalysts in alkaline media. Herein, a unique Pt–Ni/Fe coordinated single-atom Pt catalyst anchored on nickel-iron layered double hydroxide (ePt/NiFe LDH), is reported synthesized via a facile electrodeposition process within 30 min. Unlike the conventional Pt-O-M (metal) coordination, the newly discovered Pt–Ni/Fe bonding structure significantly modulates the electronic structure of the NiFe active sites, thereby synergistically enhancing both HER and OER activities. Benefiting from this optimized coordination environment and the nanoflower architecture, the ePt/NiFe LDH@e-nf electrode delivers outstanding overall water splitting performance, achieving a low cell voltage of 1.42 V at 10 mA cm −2 and 1.54 V at 100 mA cm −2 without iR compensation. More importantly, it maintains ultrastable operation over 1440 h at an industrial-level current density of 500 mA cm −2 , outperforming commercial Pt/C–RuO₂ benchmarks. This work demonstrates a promising strategy for designing high-performance and durable single-atom catalysts for practical alkaline water electrolysis applications.

Water quality monitoring refers to multiple parameters, including flow rate, pH, and temperature. However, current individual underwater sensors have certain limitations in multiparameter measurements, and integrated sensors face dilemmas, such as large size and high power consumption. In the present work, a hydrogel sensor was prepared for water quality monitoring (HSWQM) based on a piezoelectric elastomer (PE). The PE is synthesized with a long flexible backbone and cross-linking sites, providing it with a low elastic modulus and high piezoelectricity to realize stress monitoring. PE was blended with sodium alginate (SA) to make a flexible piezoelectric hydrogel (FPH), and its high swelling capacity was utilized to absorb carbon quantum dots (CQDs), thus responding to changes in pH. Further integration with a thermally sensitive alloy membrane and a Near Field Communication (NFC) module enabled real-time and synchronous monitoring of flow rate, temperature, and pH.

To address process and interface limitations in aramid honeycomb for aerospace and rail transportation, this work develops polyarylate (PAR) nanofibers with high aspect ratios using melt spinning coupled with wet dissociation, exploiting the liquid crystalline behavior of PAR to enhance molecular alignment and mechanical integrity. A scalable template thermal welding process was used to enable directional assembly and strengthen interfacial fusion in PAR nanofiber honeycomb (PAR NFHC), effectively mitigating stress concentration and delamination failures caused by fiber/resin interface mismatch in conventional aramid honeycombs. PAR NFHC demonstrates exceptional mechanical properties, with compressive strength, specific strength, and Young's modulus reaching 161 MPa, 290 kN·m·kg −1 , and 977 MPa, respectively-up to 40 times higher than commercial HC. Even after prolonged exposure to high temperatures (200 °C for 24 h) and ultraviolet radiation (24 h), PAR NFHC retains compressive strengths of 151.8 MPa and 146 MPa, respectively, with minimal degradation, whereas commercial HC experiences a substantial reduction to 1.8 MPa and 1.9 MPa. PAR NFHC exhibits excellent flexibility, enduring single-point bending at 45° and double-point bending at 30° without failure. The thermoplasticity of PAR NFHC enables closed-loop recycling, minimizing resource consumption while maintaining performance. This property positions PAR NFHC as a promising candidate for the sustainable development of high-performance honeycomb materials.

Aqueous zinc-ion batteries (AZIBs) have emerged as a promising next-generation energy storage solution due to their high energy density, abundant resources, low cost, and high safety. However, unstable zinc anode caused by side reactions and dendritic growth always severely worsens the long-term operation of AZIBs. Herein, a novel 3-cyclobutene sulfone (CS) additive was employed in the aqueous electrolyte to achieve a highly reversible Zn anode. The CS additive can offer strong electronegativity and high binding energy for the coordination with Zn 2+ , which enables its entry into the solvent sheath structure of Zn 2+ and eliminates the free H 2 O molecules from the solvated {Zn 2+ -SO 4 2− -(H 2 O) 5 }. Thus, the occurrence of side reactions and dendritic growth can be effectively inhibited. Accordingly, the Zn anode achieves long cycle-life (1400 h at 1 mA cm −2 , 1 mAh cm −2 , and 400 h at 5 mA cm −2 , 5 mAh cm −2 ) and high average coulombic efficiency (99.5% over 500 cycles at 10 mA cm −2 , 1 mAh cm −2 ). Besides, the assembled Zn||NH 4 V 4 O 10 full cell suggests enhanced cycling reversibility (123.8 mAh g −1 over 500 cycles at 2 A g −1 , 84.9 mAh g −1 over 800 cycles at 5 A g −1 ) and improved rate capability (139.1 mAh g −1 at 5 A g −1 ). This work may exhibit the creative design and deep understanding of sulfone-based electrolyte additives for the achievement of high-performance AZIBs.

Seawater splitting has been considered an environmentally friendly and cost-effective method for hydrogen production. However, developing efficient electrocatalysts capable of enduring the severe corrosive conditions of natural seawater for extended durations remains a notable technical challenge. Herein, the Ni 3 S 2 -supported NiFe oxalate ((NiFe)C 2 O 4 /Ni 3 S 2 ) nanorod arrays were synthesised through hydrothermal and impregnation precipitation methods. Structural and spectroscopic analyses revealed that the (NiFe)C 2 O 4 /Ni 3 S 2 catalyst formed an integrated oxide-sulfide interface with coexisting Ni–O/Ni–S coordination. This dual coordination environment, coupled with the presence of Fe in a higher oxidation state, confirmed interfacial electronic reorganization characterized by directional electron transfer from Ni to Fe. The resulting charge transfer pathway enhanced the electron delocalisation between active centers, thereby improving active site utilisation. The obtained (NiFe)C 2 O 4 /Ni 3 S 2 demonstrated remarkable catalytic activity for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in a simulated alkaline seawater solution (NaCl + KOH), with overpotentials of 363 mV (HER) and 295 mV (OER) at a current density of 500 mA cm −2 for industrial electrolysis requirements and remarkable stability over 100 h of durability testing. Additionally, the (NiFe)C 2 O 4 /Ni 3 S 2 electrode pairs only required a cell voltage of 1.81 V to achieve 100 mA cm −2 with Faradaic efficiency of 98 % in 1.0 M KOH + seawater. This study presents a novel approach for fabricating multifunctional electrocatalysts, providing a promising pathway for advancing seawater electrolysis and supporting the development of cost-effective green hydrogen production technologies.

Eliminating the capping action of fine serpentine particles has been a long issue in the pyrite flotation. Herein, the hydrolytic poly(maleic anhydride) (HPMA) was adopted to impede the fine serpentine particles to approach the pyrite surface hydrophobized by sodium isobutyl xanthate (SIBX). Its impeding performance was compared with citric acid (CA), oxalic acid (OA) and glycolic acid (GA). The micro-flotation results indicated that 8.0 mg/L HPMA could effectively eliminate the depression of the fine serpentine particles against pyrite, and enhance the pyrite recovery from about 21 % to 89 %. The findings of contact angle, optical microscope, Zeta potential, adsorption capacity and FT-IR inferred that HPMA selectively adsorbed on serpentine surface, and transformed the hydrophobic attraction between serpentine and SIBX-hydrophobized pyrite into electrostatic repulsion, which made serpentine approach pyrite surface difficultly. In addition, the elimination efficiency of four carboxylic acids against serpentine coating was ranked as HPMA > > CA > > OA > GA, which was positively in accordance with the number of carboxylate group(s) in their molecules. Thus, HPMA efficiently impeded the approach of fine serpentine particles onto the hydrophobized pyrite.

Achieving efficient photocatalytic CO 2 reduction using H 2 O as a hydrogen source requires the synergistic optimization of both charge and proton transfer between CO 2 reduction and H 2 O oxidation half-reactions. However, conventional studies mostly focused on enhancing these half-reactions independently, overlooking the intrinsic interdependence between them. Herein, this work develops a photothermal catalyst (denoted as Pd 1+c /3DOM-In 2 O 3 ) through engineering synergistic Pd single atoms (Pd 1 ) and Pd clusters (Pd c ) in three-dimensional ordered macroporous (3DOM) In 2 O 3 framework. The mechanistic study reveals that the coexistence of Pd single atoms and clusters not only offers synergistic active sites to promote the reaction of CO 2 and H 2 O, but also substantially improves the separation and transfer efficiencies of photogenerated electrons and holes. The Pd clusters facilitate H 2 O dissociation to ensure an adequate supply of active hydrogen species as well as synergistically enhance the adsorption and activation of CO 2 at Pd single-atom sites. Furthermore, the enhanced photoabsorption in visible and near-infrared regions, attributed to the localized surface plasmon resonance of Pd clusters, leads to a significant increase in catalyst temperature under simulated solar irradiation. The integration of photocatalysis with the photothermal effect affords an intensified driving force for the selective conversion of CO 2 and H 2 O into CO, thereby accelerating the reaction kinetics of the overall photocatalytic CO 2 reduction process. As a result, the Pd 1+c /3DOM-In 2 O 3 catalyst exhibits excellent performance for solar-driven CO 2 reduction with H 2 O vapor, achieving a remarkable CO production rate of 192.52 μmol g –1 h –1 , which is 19.8-fold and 12.2-fold higher than those of pure 3DOM-In 2 O 3 and Pd 1 /3DOM-In 2 O 3 , respectively. This study provides valuable insights into the synergistic effect of metal single atoms and clusters toward both efficient photocatalysis and photothermal effect for solar-driven CO 2 reduction.

There will be a rapid rise in manufacture and use of lithium-ion batteries (LIBs), largely driven by the electrification of transport, such as electric vehicles. However, end-of-life LIBs will pose major resource and environmental challenges without low-cost, effective recycling. Herein, we report an economically feasible kilogram-scale upcycling strategy to convert spent LIB cathode materials into NiCoMnFeP (NCMFP) electrocatalysts. These nanoparticles self-assemble into a gradient architecture, boosting stability in harsh direct seawater electrolysis, with an ultra-low oxygen evolution reaction (OER) overpotential increase rate (OIR) of 1.27 × 10 −4 V h −1 and excellent durability (OIR = 2.48 mV/°C) under 0–400 mA cm −2 , 30°C–90°C, and 8–13 pH. The NCMFP-based anion-exchange membrane electrolyzer achieves 500/1,000 mA cm −2 at 1.78/1.99 V, maintaining stability over 120 h. Economic analysis shows a high-value utilization cost of only 18.2 RMB g −1 , significantly lower than LiNi 1-x-y Co x Mn y O 2 (NCM) recycling/regeneration. This work provides new insights for battery upcycling and designing high-performance electrocatalysts for seawater splitting.

A hierarchical nanofibrous membrane functionalized with CoO-ZnO nanocomposites was developed to efficiently degrade organic pollutants and inhibit pathogenic microorganisms in water. The membrane's stable structure minimized metal ionic leaching during degradation processes. Fabricated using a combination of electrospinning and hydrothermal growth, the membrane demonstrated enhanced degradation and antimicrobial properties. At a dosage of 0.2 mg/mL with 25 mM H 2 O 2 , the membrane achieved 99.5% removal of methylene green oxalate within 9 min, with a rate constant of 0.5748 min −1 and a mineralization rate of 39.2%, demonstrating excellent degradation performance. Moreover, the membrane exhibited exceptional bacteriostatic activity, inhibiting Escherichia coli and Staphylococcus aureus by 98.95% and 98.76%, respectively. Mechanistic studies revealed that the CoO-ZnO heterojunction enhanced ROS generation, with O 2 • − as the dominant species, enabling both dye degradation and antibacterial activity through a unified oxidative mechanism. XRD analysis and cyclic degradation tests confirmed structural stability, with 86.6% efficiency retained after three cycles. The hierarchical architecture, combining the CoO-ZnO nanocomposite heterojunction and nanofibrous support, improves interaction with pollutants and bacteria while minimizing catalyst loss. This study highlights a new strategy for designing bimetallic Fenton-like nanofibrous membranes with integrated degradation and antimicrobial functions, providing guidance for advancing catalytic water treatment materials.

Petroleum-based plastics are a significant source of global environmental pollution due to their non-biodegradability. Polylactic acid (PLA), a bio-based and biodegradable polymer, appears to be a promising alternative. However, PLA’s slow degradation rate and formation of persistent residues limit its practical application in agriculture. PLA breakdown can be accelerated by designing stable catalysts, such as through immobilization strategies. Enzyme supports can microregulate the surrounding microenvironment, thereby enhancing enzyme–substrate interactions. Herein, we first design an enzyme–cellulose nanocrystal interface to regulate the microenvironment for the degradation of polylactic acid (PLA) films. By grafting Proteinase K (ProK) onto carboxylated cellulose nanocrystals (HSCNC) and incorporating the resulting Pro-HSCNC into PLA matrix, a composite (PCPro) was developed that demonstrates enhanced crystallinity and mechanical strength while preserving ProK enzymatic activity. The Pro-HSCNC not only introduces multiple degradation sites effectively but also enhances water retention and microbial growth, thereby actively managing the local environment to enable faster, controlled degradation. As a result, PCPro reaches up to 29.5% degradation in soil within 120 days while also supporting plant growth, surpassing most PLA composites in degradation performance. Life cycle assessment (LCA) of PCPro shows a significantly lower environmental impact compared to conventional PLA. This work introduces a new approach for designing enzyme-active bio-polyester-based materials with programmable degradation behaviors through enzyme–cellulose interfacial interaction.

Ionic pre-insertion is considered to be an effective method of modulating the interlayer structure of vanadium oxides, allowing for greater interlayer spacing and more active site exposure. However, the pre-inserted ions inevitably compete with the V atoms for the O atoms, leading to irreversible stretching distortion of the V O bond and thus reducing the stability of vanadium oxides. Herein, we inhibit the competitive displacement of oxygen atoms in vanadium oxides due to pre-inserted NH 4 + ions by utilizing Na + instead, and thus the obtained NaNHVO demonstrated impressive cycling stability (capacity retention of 86 % for 10,000 cycles at 10 A g −1 ), fast ion inserted/de-inserted kinetics, and highly competitive specific discharge capacity (465.6 mAh g −1 at 0.1 A g −1 ). The variation of the V O bond lengths of NaNHVO and its unique ion transport pathway are verified by a combination of DFT calculations and experiments. In addition, the electrochemical energy storage mechanism of Zn 2+ /H + co-storage of NaNHVO is determined by tracking the changes in the electrode structure at different charging-discharging stages. This work provides new insightful ideas for improving the ion pre-insertion method and thus designing rational layered vanadium oxide electrode materials.

Addressing the inhibitory influence of the oxide layer on the ignition and combustion of aluminium particles stands as one of the pivotal factors in facilitating its utilisation as an amphibious fuel. In this investigation, leveraging the distinctive properties of oxalic acid (OA), which is prone to decomposition and gas generation and holds substantial optimisation potential, surface modification of aluminium particles was conducted in conjunction with boron and magnesium particles. Al-based amphibious energetic composites (AEC) were thereby synthesised. Subsequently, their thermal behaviour, ignition and combustion characteristics, and action mechanism were investigated. The results indicate that the thermal behaviour of AEC samples encompasses dehydration, decomposition, and oxidation stages under amphibious atmospheres (namely, air, water vapour, and their mixtures). The atmosphere exerts a minimal influence on the thermal behaviour. Additives can remarkably enhance the ignition and combustion performance of aluminium particles. Owing to the readily decomposable OA and magnesium oxalate (OM) adsorbed on its surface and the highly reactive Mg particles, the ignition delay time of AEC in amphibious atmospheres is shortened by approximately 45–67 ms. Nevertheless, OA and OM merely function in particle dispersion. Consequently, the oxidising atmosphere in the environment has a substantial impact on the combustion performance of AEC samples. When O₂ is preponderant, the surface reactions of B and Mg clusters on the surface of aluminium particles release heat, thereby facilitating the combustion (the maximum combustion temperature is increased by approximately 600 K). When H₂O is dominant, this combustion-promoting effect diminishes. During combustion, the formation of metal oxides with high melting and boiling points, such as MgO, impedes the contact between the core active metals and oxidising gases, thereby reducing the self-sustained combustion performance of AEC samples. This research will offer crucial insights for the development and application of amphibious metal fuels.
