Ice formation on surfaces causes substantial economic losses and safety hazards, driving an urgent need for comprehensive anti-icing strategies that remain scientifically and technically challenging. In this work, a fluorine-free photothermal superhydrophobic coating was prepared on Q235 carbon steel via electrostatic powder spraying, integrating anti-icing, deicing, corrosion resistance and robust mechanical stability. The coating was constructed with modified SiC powder, modified SiC gel, and phenolic resin (PF) as the main photothermal components. The resulting material exhibited excellent superhydrophobicity, with the modified SiC gel enhancing interfacial interactions between the coating and the substrate, thereby improving mechanical durability and weather resistance. Electrochemical tests in 3.5 wt% NaCl solution confirmed its outstanding anti-corrosion performance. Under simulated sunlight exposure, the coating demonstrated highly efficient light absorption and photothermal conversion capabilities, achieving complete water droplet shedding in just 11 s, which indicates its outstanding anti-icing and de-icing performance under the combined active and passive effects. At −20 °C, the ice formation time on the treated surface was delayed by 6.5 times compared to the untreated surface. The prepared coating features high mechanical strength, environmental friendliness, and efficient anti-icing/de-icing properties, offering a promising strategy for long-lasting anti-icing protection in practical applications.

The development of efficient, stable, and low-cost bifunctional oxygen electrocatalysts remains a key challenge hindering the commercialization of rechargeable zinc-air batteries (ZABs). This study presents a facile room-temperature polymerization and solvothermal strategy based on benzoxazine ring-opening polymerization to construct an integrated photothermal electrocatalyst (PTBOZ-60-NC-Fe 3 O 4 ) composed of nitrogen-doped carbon aerogel and Fe 3 O 4 nanoparticles. The catalyst features a hierarchically porous structure with a high specific surface area (up to 1702 m 2 g −1 ) and constructs Fe–N/O dual-active sites through interfacial bonding. Under photothermal assistance, it exhibits enhanced bifunctional activity for the oxygen reduction and evolution reactions (ORR/OER), achieving a low potential gap (ΔE) of 0.636 V, which is among the best reported values and surpasses most state-of-the-art catalysts. When applied in a ZAB, it delivers a high power density of 200.5 mW cm −2 and excellent cycling stability, maintaining stable operation for over 2760 cycles even at −30 °C. This work provides a simple and effective material design strategy for high-performance electrocatalysts suitable for demanding environments, particularly for harsh-environment-adaptable energy storage devices.

The electrocatalytic nitrate reduction reaction (NO 3 RR) to ammonia (NH 3 ) presents a sustainable pathway for wastewater treatment and green NH 3 synthesis. However, developing catalysts that simultaneously achieve high activity, selectivity, and stability over a wide pH range remains a challenge due to the inadequate supply of active hydrogen (*H). Herein, an efficient Cu 3 P hollow nanocubes (Cu 3 P-HNCs) electrocatalyst has been successfully designed for high-performance NO 3 RR over a wide pH range. The as-prepared Cu 3 P-HNCs exhibit excellent performance for NO 3 RR, achieving NH 3 yield rates of 19.77, 26.04 and 12.39 mg h −1 mg cat −1 in neutral, alkaline and acidic electrolytes, respectively. The experimental results and theoretical calculations prove that the hollow cubic architecture endows the Cu 3 P-HNCs with a high specific surface area and multiple catalytic active sites, while phosphoration induces a favorable downshift in the d-band center. This electronic optimization weakens intermediate adsorption and effectively reduces the energy barrier of the key reaction step, ultimately leading to the distinct NO 3 RR performance. This study elucidates a synergistic design strategy and offers insights into designing efficient and robust electrocatalysts for NO 3 RR across a broad pH range.

The Bi O bond is widely regarded as the key motif for CO 2 electroreduction towards formate, but the role of specific Bi O coordination remains unclear. Herein, we study the electrocatalytic behavior of a Bi 4 Ti 3 O 12 perovskite containing Bi O 6 and Bi O 7 structures. Under 24-h CO 2 reduction reaction (CO 2 RR), Bi 4 Ti 3 O 12 reconstructs into Bi 2 O 2 CO 3 while retaining Bi O 7 and maintaining high formate Faradaic efficiency (FE). In contrast, electrochemical measurements and in-situ attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) confirm Bi 2 O 3 lacking Bi O 7 favors hydrogen evolution reaction (HER). Density functional theory (DFT) calculations indicate Bi O 7 lowers the energy barrier for *OCHO generation, identifying it as the key active site. Using a solid-state electrolyte (SSE) reactor, pure formic acid (0.19 M) is continuously produced with ∼70% FE over 48 h. This work indicates that the coordination environment of Bi O motif displays an essential role in selectivity, and that the Bi O 7 motif might be the critical active site for formate production.

Developing advanced photothermal effect photocatalysts to maximize solar utilization receives increasing attentions in photocatalytic H 2 production. Herein, a Ni-doped Zn 0.7 Cd 0.3 S (Ni-ZCS-20) integrating photothermal material and photocatalyst was constructed via simple one-step hydrothermal method. Successful incorporation of Ni into Zn 0.7 Cd 0.3 S was confirmed by various characterization techniques including XRD, XPS, SEM and TEM. Under photothermal-assisted condition, the Ni-ZCS-20 offered a superfast H 2 generation rate, reaching as high as 183 mmol/g·h, which exhibited enormous advantages over existing photocatalysts. Detailed mechanism explorations verified that such a high H 2 generation rate of Ni-ZCS-20 could be attributed to the lowed H 2 generation overpotential, broadened light absorption region, and promoted photogenerated carrier separation originating from the Ni doping. In addition, the doped Ni partly substituted the Zn in Ni-ZCS-20, providing an extra channel for photogenerated electrons and efficiently hindering the recombination of electron-hole pairs. Density functional theory (DFT) calculations demonstrated that Ni incorporation into ZCS effectively tailored its electronic structure, enhanced surface electron-supply capability, and optimized hydrogen adsorption, thereby leading to superior catalytic performance of Ni-ZCS toward HER. This finding provides valuable guidance for constructing photothermal effect materials to exploit full spectrum solar in photocatalytic H 2 evolution.

Developing high-performance structural materials from fast-renewable biomass is an effective strategy to reduce dependence on fossil resources and mitigate CO 2 emissions. Here, we report a scalable, water-only process that transforms fast-growing bamboo into robust structural materials through hydrothermal-assisted disintegration followed by thermal self-bonding. Subcritical water treatment softens cell walls and enables the controlled separation of high-aspect-ratio (>3000) macrofibers, while inducing the selective lignin migration and surface enrichment. During subsequent hot-pressing, this mobilized lignin undergoes in-situ condensation and interfacial crosslinking, forming a continuous, load-bearing network that reinforces a densely hydrogen-bonded cellulose microfiber framework. Reducing the macrofiber diameter to 100 μm significantly increases the specific interfacial area and promotes microfiber alignment, yielding fully adhesive-free structural materials with exceptional mechanical performance, including a tensile strength of 580 MPa, a flexural strength of 228 MPa, and a toughness of 4.35 MJ/m 3 , surpassing conventional adhesive-bonded fiberboard by 3–5 times. Life-cycle assessment reveals more than a 60% reduction in fossil carbon input and CO 2 emissions relative to petroleum-based plastics. This work demonstrates a green and generalizable strategy for lignocellulosic biomass valorization through programmed lignin activation and chemical-free consolidation, providing sustainable production of high-performance bio-based structural materials with a minimized environmental footprint.

The alkaline hydrogen evolution reaction (HER) is crucial for a sustainable hydrogen economy but remains hindered by the slow dissociation of water and the difficult adsorption/desorption of hydrogen intermediates (*H). To address these dual challenges, we introduce a lattice expansion strategy via the incorporation of larger-radius Co 2+ into a NiCoP electrocatalyst. XRD, HRTEM, and XPS analyses reveal a significant lattice expansion of up to 3.2%, which effectively modulates the electronic structure, promoting electron transfer from Co and Ni to P. Electro-response tests further verify that the NiCoP catalyst with optimal lattice expansion control exhibits enhanced water dissociation and an appropriate *H binding capability. These synergistic effects endow the platform with an ultra-low overpotential of 23 mV at −10 mA cm −2 in 1 M KOH. When integrated into an alkaline water electrolyzer, the NiCoP platform requires only a cell voltage of 2.2 V at −500 mA cm −2 and demonstrates superior stability for over 600 h.

On-site electrochemical synthesis of hydrogen peroxide (H 2 O 2 ) for advanced oxidation processes is a promising technology, yet its practical application is hindered by poor performance at industrial-scale current densities (>500 mA cm −2 ). This limitation stems from severe mass transport bottlenecks for both oxygen and protons. Here, we report a strategy to overcome this dual challenge by designing a self-stratified porous catalyst layer (D-CL) using a volatile fluorinated additive. The additive's evaporation creates abundant macropores that enhance O 2 permeation, while residual -CF x fragments restructure the interfacial water network from rigid tetrahedrally coordinated water to flexible doubly hydrogen-bonded water configurations. This tailored interface weakens hydrogen bonding, facilitating rapid proton transport and mitigating local pH increases. This synergistic design enables a high H 2 O 2 Faradaic efficiency of ∼60% and a production rate of 8.0 mmol cm −2 h −1 at 0.8 A cm −2 , demonstrating a robust pathway for practical environmental remediation applications.

Polyvinyl alcohol (PVA) is a promising biodegradable polymer, but its widespread application is critically constrained by inherent flammability, limited UV resistance, and the mechanical compromises often incurred by conventional flame-retardant modifications. To address these challenges, a novel bio-based phosphorus‑nitrogen synergistic flame retardant (DPP) was developed from pyridoxal phosphate via a facile Schiff base condensation and P H addition route. This well-designed DPP was efficiently incorporated into PVA via a green melt blending process, yielding composites that achieved a simultaneous enhancement of multiple properties. With a 10 wt% DPP loading, the composite exhibited exceptional flame retardancy, achieving a limiting oxygen index (LOI) of 30.5%, a UL-94 V-0 rating, along with a 63.2% reduction in its peak heat release rate (PHRR) and a 32.7% decrease in total heat release (THR). Additionally, it provided outstanding UV shielding performance, with an ultraviolet protection factor (UPF) of 362 and over 99.7% blocking of both UVA and UVB radiation. Impressively, its tensile strength was enhanced to 25.2 MPa, thus overcoming the common performance trade-off. This multifunctionality stems from DPP's well-orchestrated molecular design: it operates through a vapor- and condensed-phase synergistic flame-retardant mechanism and intrinsic UV absorption, while its strong interfacial hydrogen bonding with PVA constructs a physical crosslinking network, underpinning the concurrent mechanical enhancement. This work presents a strategy for fabricating sustainable, high-performance, multifunctional PVA materials. The PVA/DPP composites obtained via this strategy show promising potential for advanced applications such as outdoor protection and safe electronics packaging.

The ever-growing demand for electricity and clean water restricts widespread application of hydrogen production via water electrolysis or photocatalytic water splitting. Here, we present a self-sufficient electricity-free air-to-hydrogen system that integrates radiative cooling-enhanced water adsorption with synergistic photocatalysis and photothermal conversion by fabricating spectral selective absorbing/emitting hygroscopic hydrogen evolution nanofiber membranes to harvest atmospheric moisture and produce hydrogen. Leveraging the nocturnal radiative cooling effect, we expand the operational relative humidity range of nanofiber membranes and enhance both water collection capacity and kinetics. The collected water undergoes efficient gas-phase water splitting for H 2 production during the day through photothermal catalytic processes without electrical and liquid water assistance. The hydrogen production rate of the scale-up air-to-H 2 system under outdoor natural light reaches 6467.55 µmol·m -2 ·h -1 . Extrapolating this experimentally validated rate to land-based deployment demonstrates the potential for large-scale hydrogen generation, with practical feasibility dependent on regional humidity and solar conditions. Thus, our approach cost-effectively addresses green-H 2 scarcity without demanding natural freshwater and electricity, thereby providing an archetype for global sustainable development. Rising electricity and freshwater needs limit conventional hydrogen production. Here, the authors report a self-sufficient, electricity-free system that harvests atmospheric moisture to produce green hydrogen, offering a scalable and sustainable path to alleviate global green-hydrogen scarcity.

Metal-organic framework (MOF)/photothermal composites typically suffer from the intrinsic trade-off between adsorption capacity and photothermal regeneration efficiency, limiting their synergistic adsorption-desorption performance. Cu-based MOF (HKUST-1) crystals were grown on photothermal inverse opal polypyrrole (IOPPy) with abundant surface pyrrole N sites (metal coordination) by microwave-assisted in-situ method and successfully constructed IOPPy(Cu)@HK-M. The abundant N-Cu-O interface bridging in IOPPy(Cu)@HK-M ensured ultrahigh MOF loading (90 wt%) and induced the formation of unsaturated Cu and interface micropores. It enhances toluene capture capacity (1.5 times, P / P 0 = 0.0026) and adsorption kinetics (1.8 times) compared to HKUST-1. During photothermal desorption process, photon localization effect of inverse opal structure significantly enhances the photothermal conversion efficiency to 54%, which is 2.2 times of HKUST-1. The inverse opal structure also promotes efficient energy transfer throughout the system after light conversion and reduces internal temperature gradient, and act on MOFs via N-Cu-O interface, thereby accelerating the desorption of toluene within the MOFs. Hence, IOPPy(Cu)@HK-M achieves a remarkable 99.7% desorption ratio and 2.9 times desorption rate versus HKUST-1 under same energy input. The construction of inverse opal-MOF successfully achieves synergistic enhancement of toluene adsorption/desorption with high efficiency and low energy consumption by reinforcing photothermal conversion efficiency and mass/heat transfer capabilities.

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.
