Layered double hydroxides (LDHs) have emerged as promising photocatalysts for effective pollutant degradation in wastewater treatment. In this study, a visible-light-responsive ZnO/In 2 O 3 composite photocatalyst incorporated with biomass-derived carbon ( [email protected] ) was synthesized via controlled calcination of Zn/In-containing binary LDH precursors with biomass carbon sources. The optimized [email protected] composite demonstrated remarkable performance in synergistic adsorption and photocatalytic degradation of crystal violet (CV), achieving high degradation efficiency (97.46 %) for 2000 mg/L CV under 460 nm LED light - significantly superior to the 54.79 % efficiency of pristine ZnIn-LDO. The photodegradation kinetic constant of [email protected] was 8.4 times higher than that of ZnIn-LDO. Systematic characterization revealed that the optimal BC incorporation engineered the optical and surface properties: it narrowed the bandgap, enhanced visible-light absorption, increased specific surface area, and most importantly, drastically promoted the separation and transfer of photogenerated carriers. Mechanistic studies identified that the improved charge dynamics drive an efficient oxygen reduction pathway, where superoxide radicals (·O 2 − ) and hydroxyl radicals (·OH), generated via H 2 O 2 intermediates, serve as the dominant active species. The degradation intermediates exhibited reduced phytotoxicity. This work provides a novel strategy for developing high-performance LDH-based photocatalysts by coupling biomass carbon to optimize interfacial charge separation and reaction kinetics.

Passive radiative cooling provides a sustainable, zero-energy cooling pathway, yet it faces a fundamental challenge in humid or cloudy conditions due to the blockage of the atmospheric transparency window and increased downward atmospheric radiation. Herein, we present a hierarchical Janus bilayer metafabric (TS/PLU) that synergistically combines radiative and evaporative cooling for thermal management with humidity resilience. Integrating a hydrophobic TPU/h-SiO 2 reflection layer with a hygroscopic PAN/LiCl@UiO-66 regulation layer achieves superior solar reflectance (>96%), high atmospheric-window emissivity (96.6%), and moisture capture and evaporation. Crucially, a “harvest-storage-release” mechanism is enabled by UiO-66-confined LiCl, mitigating deliquescence and salt leakage while facilitating heat dissipation even when radiative power is attenuated by high humidity. Asymmetric wettability ensures unidirectional water transport, preserving the radiative function of the hydrophobic top layer. Outdoor tests demonstrate a maximum sub-ambient temperature reduction of 13.4°C under sunny conditions, with a net radiative cooling power of 132.87 W m −2 . The LiCl@UiO-66 incorporation contributes an additional 5.1°C cooling enhancement relative to non-hygroscopic controls. Combined with mechanical robustness (≈370% elongation) and washing durability, this multimodal strategy offers a material-level proof of concept for thermal management featuring humidity resilience and shows potential relevance to personal cooling, outdoor thermal protection, and building-envelope cooling.

In semiconductor photocatalysis, the strong redox ability of a wide band gap and the broad light absorption range of a narrow band gap are a pair of irreconcilable trade-offs. By combining semiconductors with different band gap widths and band edge positions, both of these advantages can be achieved simultaneously. A ternary Cu2O-SnO2/g-C3N4(CuSnCN) composite photocatalyst was prepared through the hydrothermal and calcination method. Structural analyses confirm the successful integration of truncated octahedral Cu2O, spherical SnO2, and layered g-C3N4, which extends the visible-light response to 650 nm. The optimized system achieves a remarkable 96.58% degradation of methyl orange (80 min, 0.2 g/L catalyst, pH = 3) through dual heterojunction synergies: p–n junctions (Cu2O/g-C3N4and SnO2/g-C3N4) and Z-scheme charge transfer (SnO2/Cu2O), with •O2−/h+identified as the dominant reactive species. This work establishes a tunable heterojunction platform for the elimination of multiple pollutants through engineered radical-generation pathways.

Overall, this work presents a feasible strategy for treating complex water bodies. Scheme 1. Flow chart for the preparation of PAMX aerogel. Solar interfacial evaporation has emerged as a potential solution for wastewater treatment due to its high energy utilization efficiency. However, evaporators often face problems such as limited photothermal conversion capacity, poor stability, and insufficient water supply. In this study, an MXene-PVA@AG composite aerogel evaporator (PAMX) with vertically oriented channels is fabricated via directional freeze drying. Utilizing the broad-spectrum absorption of MXene and the continuous water supply from the PVA/AG porous network, synergistic regulation of solar absorption, localized heat management, and water transport is achieved. Results show that the PAMX evaporator exhibits an evaporation rate of 1.82 kg·m −2 ·h −1 under 1 sun illumination, corresponding to a photothermal conversion efficiency of 97.22%, while maintaining stable output under different light intensities. Owing to the excellent photothermal conversion performance of MXene, the PAMX evaporator exhibits remarkable purification effects on metal salt ions and organic dyes, such as MO and MB. Furthermore, using polyvinyl alcohol and agarose as matrix materials endows the evaporator with good structural stability, allowing it to maintain high evaporation rates even after one week of continuous evaporation, and sustain strong evaporation performance in oil-containing systems. Overall, this work presents a feasible strategy for the design of efficient, environmentally friendly, and pollution-resistant interfacial evaporators for treating complex water bodies.

Macrocycle-based porous organic polymers (M-POPs) are promising adsorbents for uptake of iodine vapor and adsorption of organic micropollutants (OMPs) from water. Herein, two conjugated triaryl triazine-incorporated, calix[4]pyrrole-based porous organic polymers were prepared by diazocoupling reaction between 4,4′,4′'-(1,3,5-triazine-2,4,6-triyl)trianiline (TTTA) and two configurational isomers of resorcinol-modified calix[4]pyrroles (2α,2β-C4P and 4α-C4P), referred as CP-POP-1 and CP-POP-2, respectively. The obtained CP-POPs were gifted with good porosity, high nitrogen contents and conjugated triaryl triazines, while CP-POP-1 and CP-POP-2 exhibited high iodine vapor uptake at 4.27 g/g and 4.25 g/g, respectively. Charge transfer interaction was the main mechanism for iodine vapor uptake on the CP-POPs. Besides, the CP-POPs displayed preferred adsorption feature to cationic dyes, such as methylene blue (MB), crystal violet (CV) and rhodamine B (RB), while CP-POP-2 showed superior adsorption performance towards cationic dyes. The q m values of MB, CV and RB by CP-POP-2 were as high as 317.46, 373.13 and 471.69 mg/g, respectively. Thermodynamic studies discovered that the adsorption of cationic dyes upon CP-POP-2 was a spontaneous process, while mechanism researches confirmed that electrostatic, hydrophobic and host-guest interactions were involved for adsorption of cationic dyes upon CP-POP-2. In addition, CP-POP-2 could adsorb cationic dyes efficiently from water samples containing complex matrix and exhibited good reusability. The obtained results suggested the bright prospect of the CP-POPs in removal of environmental pollutants. Download: Download high-res image (222KB) Download: Download full-size image

MnFe-O activates PMS to remove 99.34% phenol within 30 min. • Oxygen vacancies regulate Mn-Fe dual-site electronic coupling. • MnFe-O shows higher Fe 2+ and Mn 3+ contents for rapid redox cycling. • O 2 •− / 1 O 2 -coupled pathways dominate phenol oxidation in MnFe-O/PMS. • MnFe-O/PMS maintains high activity in diverse real water matrices. Peroxymonosulfate (PMS) activation technology has significant application potential in the removal of phenolic pollutants, but its catalytic performance is still limited by problems such as insufficient regulation of the electronic structure of active sites and unclear interfacial reaction pathways. This study used MnFe Prussian blue analogue (MnFe-PBA) as a precursor to construct a series of MnFe-X (X = O, S, Se) catalysts through thermal conversion and oxygen vacancy-related defect engineering, and systematically compared the effects of different vacancy types on the PMS-activated degradation performance of phenol. The results showed that the MnFe-O sample, which was jointly regulated by oxygen vacancy-related defects and structural reconstruction, exhibited the best catalytic activity, achieving 99.34% phenol removal within 30 min, with an apparent rate constant as high as 0.20 min −1 , which was significantly better than the MnFe-PBA and S/Se vacancy-regulated samples. XPS analysis showed that the increased proportions of Fe 2+ (77.25%) and Mn 3+ (70.00%) in MnFe-O created a more favorable local electronic environment for electron coupling and redox cycles. EPR and quenching results indicate that •OH, SO 4 •− , O 2 •− and 1 O 2 are generated simultaneously in the system, and an oxidation pathway dominated by O 2 •− / 1 O 2 coupling is ultimately formed. This work reveals the key role of oxygen vacancy-related defects and structural reconstruction in jointly regulating the activation of PMS by Mn-Fe dual sites, providing a new mechanistic basis for defect engineering-driven bimetallic catalyst design and efficient purification of phenolic wastewater.

Current gastroesophageal reflux disease (GERD) therapies either systemically suppress gastric acid, risking physiological disruption, or rely on antacid rafts that offer transient, non-responsive neutralization. We address this with a chemistry-centered strategy that spatially localizes proton conversion around the self-positioning raft at the gastric interface. The dynamic H + conversion equilibrium system (DH + -CES) integrates a CO 2 -generating calcium alginate raft which physically impedes reflux via its bubble-stabilized architecture for rapid interfacial self-positioning, with an engineered Lactococcus lactis expressing acid urease. Under acidic challenge, urease catalysis consumes protons locally. As pH normalizes, feedback-regulated enzymatic attenuation constrains the reaction zone, preventing bulk alkalization. DH + -CES elevates interfacial pH from 2.0 to ∼5.0 within 5 min, sustains this zone for hours while modulating only 5.38% of total fluid volume, and reduces reflux-like surge height by 38%. In an acute rat GERD model, it inhibits esophageal injury by 93.95%, downregulates key inflammatory mediators, and shows favorable biocompatibility. These findings establish DH + -CES as a proof-of-concept interface-resident chemical gatekeeper for localized, self-limiting, and physiologically respectful pH control.

Global industrialization has intensified the discharge of organic pollutants into aquatic ecosystems, with highly toxic and recalcitrant industrial wastewater emerging as a critical constraint on sustainable ecological development. Herein, a hydrogel coating fabrication strategy combining solvent-induced phase separation and nanoparticle hybridization was developed to generate hydrogel coatings with high surface roughness and uniform porous structure, addressing the trade-off between separation flux and separation efficiency that constrains conventional hydrogel oil–water separation membranes. The spatial confinement effect of these nanoparticles was leveraged in conjunction with solvent-induced phase separation to enable one-step, controllable construction of a hierarchical porous structure. This approach integrates three functions—initiation, pore formation, and functionalization—within a single nanocomponent. Based on this approach, we fabricated a zwitterionic gel membrane featuring systematic molecular- and nano-level design and assembly. TiO 2 nanoparticles are used to replace conventional photo initiators, thereby initiating the photopolymerization of sulfobetaine methacrylate (SBMA). The resulting hydrogel hybrid membrane exhibits superhydrophilicity, underwater superoleophobicity, and robust antifouling properties. It achieves > 99.5% separation efficiency for oil-in-water emulsions while enabling pollutant degradation and membrane self-cleaning through photocatalytic activity. This design strategy offers a novel paradigm for the green fabrication of advanced separation membranes and enables scalable preparation of high-performance water treatment membranes.

Oxidative polymerization strengthens PPy hydrogels and optimizes evaporation enthalpy. • Ti 3 C 2 T x -PPy multilevel channels guide salt crystallization to evaporator edges. • Ti 3 C 2 T x -PPy evaporator delivers 4.63 kg m −2 h −1 , 35% higher than PPy. Solar-driven interfacial evaporation, which relies on localized photothermal conversion at the gas-liquid interface, represents an effective strategy for seawater desalination. However, continuous salt crystallization and deposition at the evaporation interface remain a critical bottleneck that limits long-term operational stability. Herein, we develop a Ti 3 C 2 T x -PPy composite hydrogel evaporator with multilevel mass-transport channels for solar seawater desalination and spatial regulation of salt crystallization. The incorporation of Ti 3 C 2 T x optimizes the internal pore network of the polypyrrole hydrogel, establishing hierarchical mass-transport pathways that promote the preferential migration of salts towards the evaporator edges, where crystallization subsequently occurs. Meanwhile, Ti 3 C 2 T x enhances the photothermal conversion capability of the system and modulates the hydrogen-bonding structure of water molecules, thereby effectively lowering the evaporation energy barrier. Under 1 sun illumination, the Ti 3 C 2 T x -PPy evaporator achieves an evaporation rate of 4.63 kg m −2 h −1 , while maintaining a clean surface and undiminished performance after 50 h of continuous operation. The evaporator also exhibits purification efficiencies exceeding 99% in hypersaline solutions, dye-contaminated wastewater and real seawater, and delivers an average daily water yield of over 25 L m −2 under natural sunlight. This work provides a promising strategy for the design of hydrogel-based solar desalination systems with high efficiency, excellent salt resistance and long-term operational stability.

The migration and separation behavior of photoinduced electrons and holes are crucial factors for photocatalytic efficiency. Elevating the reaction temperature accelerates the kinetics of carrier migration, while the construction of heterojunctions and built-in electric fields facilitates effective carrier separation. Herein, a Bi 2 O 2 CO 3 -PbTiO 3 -PVDF sponge with outstanding photothermal piezo-photocatalytic performance was fabricated for the first time. The photocatalytic performance of Bi 2 O 2 CO 3 -PbTiO 3 -PVDF sponge is 2.69 times that of PbTiO 3 -PVDF sponge and the piezo-photocatalytic performance is better than both photocatalytic and piezocatalytic performance. The synergism of built-in electric field and photothermal effect not only accelerates carriers but also separates them, creating more active carriers for elevated catalytic performance. Furthermore, the excellent elasticity and stability make the porous flexible sponge structure suitable for practical applications. Density functional theory (DFT) calculations and finite element simulations further support the experimental data and the proposed reaction mechanism. This work focuses on the controlling of carriers through electric fields and photothermal effects, providing a novel strategy for the design and development of high-performance photocatalytic composites.

Membrane fouling critically hinders nanofiltration (NF) for dye wastewater treatment. In this work, FeOOH was in situ loaded onto g-C 3 N 4 nanosheets, and the resulting FeOOH/g-C 3 N 4 composites were embedded into polyamide (PA) layers via interfacial polymerization to fabricate a self-cleaning NF membrane. The heterojunction configuration of the FeOOH/g-C 3 N 4 composites was confirmed by SEM, TEM, and FTIR, and was observed to promote their photocatalytic oxidation under visible light. The incorporation of FeOOH/g-C 3 N 4 enhanced the surface hydrophilicity and electronegativity of the membranes. Moreover, the intercalation of FeOOH on g-C 3 N 4 endowed the PA layer with additional water channels or interfacial voids, enhancing membrane permeability while ensuring retention performance, achieving a pure water permeance of 18 L·m −2 ·h −1 ·bar −1 and rejections of > 95% for dye molecules and > 90% for divalent salts. Benefiting from the photocatalytic capability of the FeOOH/g-C 3 N 4 heterojunction, the FeOOH/g-C 3 N 4 @PA membrane exhibited improved fouling resistance and high self-cleaning properties after three reuse cycles, maintaining a flux recovery ratio of over 97%, utilizing only a simple photocatalytic degradation operation. This work may provide a new strategy for fabricating antifouling and self-cleaning nanofiltration membranes for water treatment applications.

Effective wound management is crucial for improved outcomes through timely, personalized therapies. Current dressing-based treatments lack dynamic regulation and microenvironment modulation, leading to suboptimal healing. Integrating electrical stimulation therapy with electro-controlled drug delivery promotes skin generation, ensures precise dosing, and accelerates healing. Flexible electronic patches are ideal platforms for these synergistic therapies but face challenges: rigid post-manufacture shapes and sizes limit adaptability to diverse wound geometries, and substrate materials struggle to meet both wound-healing and electronic requirements. This study develops a tailorable, transferable flexible electronic patch with a hexagonal modular design, enabling shape/size customization while maintaining electrical continuity. The water-transfer printing (WTP) technique is used to conveniently transfer conductive chondroitin sulfate (CS) hydrogel (as electrodes and drug reservoirs) and silver circuits onto clinical dressings. This method endows clinical dressings with functionality of electro-controlled drug release and electrical stimulation, simultaneously addressing substrate performance limitations of flexible electronic patches. The patch demonstrates uniform electrical signal transmission, precise electro-responsive drug control in CS hydrogels, and adaptability to wounds of different geometries. It retains electrostimulation and electro-controlled drug delivery performance after cutting, significantly promoting wound healing. This study provides a potential approach to support the advancement of flexible electronics research and clinical translation.
