Integrating derivatives of Cu-organic frameworks (CuBTC) into robust macroscopic architectures while preserving their intrinsic porosity and multifunctionality is crucial for advancing their practical application in environmental technologies. Herein, a multifunctional CuBTC-derivatives aerogel is engineered via a facile sol–gel process followed by vacuum drying for high-performance water purification. The resulting monolithic aerogel exhibits a hierarchically porous three-dimensional network with exceptional structural integrity and stability. This architecture demonstrates outstanding solar-thermal conversion capabilities, enabling highly efficient solar-driven interfacial desalination with an elevated evaporation rate and remarkable energy efficiency. Under 1 sun, the CuBTC-350-aerogel evaporator achieved water evaporation rate of 2.06 kg m⁻²h⁻¹ and efficiency of 91.5 % for pure water. The evaporator demonstrated exceptional stability, maintaining its evaporation capacity over 15 consecutive cycles of seawater desalination. Additionally, it exhibited remarkable salt-rejection performance, as evidenced by the rapid dissolution of 0.5 g of salt crystals pre-deposited on its surface under illumination. Moreover, the CuBTC-350 aerogel acts as a superior peroxymonosulfate (PMS) activator, facilitating the rapid generation of active species for the effective degradation of organic pollutants, such as tetracycline (TC) and methyl orange (MO). The synergistic coupling of solar desalination and catalytic oxidation in one integrated aerogel system offers a sustainable and versatile platform for comprehensive water treatment, harnessing solar energy simultaneously for freshwater production and contaminant destruction.

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.

Solar-driven interfacial evaporation offers a sustainable route for off-grid water purification, but achieving high evaporation efficiency and salt resistance remains a core design challenge. Herein, we propose a cross-scale integration strategy that simultaneously reduces evaporation enthalpy and enhances salt resistance. A 3D conical chitosan/polyvinyl alcohol (CSPx) aerogel-based evaporator with vertically oriented hierarchical micro-nano channels was prepared by unidirectional freezing, where polyvinyl alcohol incorporation enabled the formation of nanopores, enhanced porosity, and high-proportioned intermediate water. The optimized CSP2 achieves an evaporation rate of 2.39 kg m −2 h −1 and a solar efficiency of 100.4% under one solar intensity. For the first time, a fully coupled thermal–fluid–mass transfer COMSOL simulation revealed the surface temperature and evaporation flux distributions, clarifying the heat balance and confirming that interfacial cooling and environmental heat harvesting enable the conical structure to exceed 100% efficiency. The evaporator enables directional salt crystallization at the cone apex in 5 wt% NaCl solution and exhibits strong antibacterial activity, excellent purification performance for seawater, heavy-metal wastewater, and dye-contaminated water, as well as outstanding potential for practical applications. To sum up, this research provides insights into the performance optimization of solar evaporators and highlights the potential applications in alleviating the global freshwater crisis.

Dye-contaminated wastewater from the textile and dyeing industries poses severe environmental and health risks due to the persistence and toxicity of synthetic dyes. To address this issue, sodium alginate (SA)-based composite gel microspheres were fabricated via ionic crosslinking with calcium chloride followed by acid exchange to enhance structural stability and adsorption performance. Two types of functionalized adsorbents were synthesized and optimized: SA modified, and with stearyltrimethylammonium chloride (SA/S-H) and SA co -functionalized with poly(sodium 4-styrenesulfonate) (SA/S/PS-H). Comprehensive characterization using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) confirmed the successful preparation and compositional uniformity of the adsorbents. Adsorption kinetics for methylene blue (MB) followed the pseudo-second-order model, reaching equilibrium within 6 h， while isotherm data fitted the Dubinin-Radushkevich (D-R) model. Notably, the incorporation of PSSS significantly enhanced the adsorption capacity; at 45 °C, SA/S/PS-H achieved a remarkable maximum adsorption capacity of 900.91 mg/g, compared to 612.61 mg/g for SA/S-H. The dominant adsorption mechanisms were identified as electrostatic attraction, micropore filling and hydrogen bonding. Furthermore, the microspheres showed excellent reusability despite the interference of co-existing cations. This study presents a simple and scalable approach for constructing high-performance bio-based adsorbents with significant potential for sustainable and practical treatment of dye-laden wastewater.

Solar energy, as a renewable and clean energy source, is utilized to obtain freshwater and power generation, serving as a sustainable solution to address water scarcity and power shortages. This study proposes a strategy for power generation based on salinity gradients and designs an inclined composite evaporator. The evaporator features a nickel foam substrate functionalized through cross-linking of sodium alginate (SA) and tannic acid (TA) with trivalent iron ions (Fe 3+ ), enabling efficient electricity generation and freshwater production, named as SA/TA-Fe@Ni. (“Fe” indicates trivalent iron ions (Fe 3+ ) crosslinking) The TA-Fe 3+ coordination complex formed in situ on the evaporator surface appears black and exhibits excellent broad-spectrum light absorption capability. The evaporator is designed with an inclined configuration, which can significantly enhance the water transport performance. The enhanced evaporation flux establishes a stable salinity gradient at the interface, which constitutes the core driving mechanism for salinity gradient power generation. The inclined SA/TA-Fe@Ni evaporator achieves an evaporation rate of 2.14 kg•m −2 •h −1 under standard sun irradiation (one sun). It simultaneously demonstrates excellent seawater desalination and wastewater purification, while generating an open-circuit voltage of 83.7 mV. The system demonstrates outstanding salt tolerance, stability, durability, and environmental adaptability, fully demonstrating the potential of practical applications.

In this study, TiO2 and anhydrous Na2CO3 were used as precursor materials to investigate the optimal conditions for synthesizing sodium titanate (Na2Ti3O7) by the molten salt method. The sodium titanate reactant was acid-exchanged to prepare titanic acid (H2Ti3O7), which was then calcined at different temperatures for varying durations. The resulting product was characterized by XRD, SEM, TEM, FE-SEM, and FTIR, confirming the formation of an H2Ti3O7/TiO2 composite. The photocatalytic degradation performance, mechanism, and stability of the H2Ti3O7/TiO2 composite were evaluated using rhodamine B as a model pollutant. The results indicated that the composite calcined at 800 °C for 3 h exhibited the fastest degradation rate. After the addition of peroxymonosulfate, the degradation efficiency reached approximately 100% within 30 min, which was higher than those of pure H2Ti3O7 and TiO2. The composite retained 94.56% of its original efficiency after four cycles, indicating excellent catalytic degradation ability. Quenching experiments revealed that the main active species were SO4˙−, ˙O2−, and ˙OH, and a possible degradation mechanism was proposed.

Layered double hydroxide (LDH) membranes, featuring uniform interlayer nanochannels, hold substantial potential for molecular sieving in aqueous solutions. In this study, polyethyleneimine (PEI) rich in amino groups is used as bridging unit to develop a robust PEI-bridged-LDH composite membrane with enhanced molecular sieving performance. The introduction of PEI bridges adjacent nanosheets, strengthens the interlayer bonding strength, creating a continuous LDH nanosheet membrane with high selectivity. Owing to the well-designed lamellar structure ans excellent hydrophilicity, the PEI-bridged-LDH composite membrane achieves high water permeance (864.5 L m −2 h −1 bar −1 ) and superior dye/salt separation performance, with outstanding dye rejections (e.g., Congo Red: 99.1%, Methyl Blue: 99.3%, Victoria Blue B: 99.7%) and low salt rejections (e.g., Na 2 SO 4 : 5.7% and NaCl: 2.2%). Moreover, the PEI-bridged-LDH composite membranes show high mechanical strength due to the hydrogen bond interactions between PEI and LDH nanosheets, thereby exhibiting robustness against mechanical damage and under high trans-membrane pressure of 5 bar. Besides, the composite membrane also demonstrates outstanding anti-fouling properties and long-term operation durability for dye/salt mixtures, suggesting its great potential in treating practical textile wastewater. This work opens a new avenue for developing robust LDH membranes for continuous and stable dye/salt separation.

The construction of semiconductor heterojunctions offers a promising route to markedly enhanced photocatalytic performance. A template-based and electrostatic self-assembly strategy was employed to synthesize the mesoporous g-C₃N₄/MXene photocatalyst, integrating melamine-derived g-C₃N₄ with an MXene secondary phase. MXene layers were inserted between g-C₃N₄ layers to construct a special stacked sandwich structure called a 2D/2D heterostructure. The mesoporous g-C₃N₄/MXene composite delivers markedly superior photoelectrochemical performance to bare mesoporous g-C₃N₄. With 10 wt % MXene, the as-prepared g-C₃N₄/MXene attains its maximum BET surface area of 43.19 m²g⁻¹ and simultaneously delivers the highest photocatalytic activity. After 120 min of visible-light irradiation, it degrades 98.6 % of methyl orange and 97.2 % of rhodamine B, while retaining excellent cyclic stability. The construction of a heterojunction between MXene and mesoporous g-C₃N₄ can significantly reduce the band gap of g-C₃N₄, causing a redshift of the UVvis absorption edge, and effectively improve the separation efficiency of photogenerated electron-hole pairs during photoresponse. After cyclic testing, the degradation efficiency showed no significant decline, demonstrating excellent catalytic stability. These findings synthesize an economical, versatile, and efficient mesoporous g-C₃N₄/MXene photocatalyst, which can be used to eliminate pollutants in industrial wastewater streams and improve environmental sustainability.

The development of multifunctional membranes capable of simultaneous oil-water separation and organic pollutant degradation remains a significant challenge. In this study, we investigate a PTFE-based composite membrane modified with l -DOPA tert-butyl ester and PEI hydrophilic coating and functionalized with ZIF-67 and NiOOH, focusing on its surface physicochemical properties, oil-water separation performance, and organic pollutant removal efficiency. The modified membrane activates peroxymonosulfate (PMS) to establish an efficient electron transfer pathway, accelerating the Co/Ni redox cycles and thereby enhancing organic pollutant degradation. The membrane exhibits superior hydrophilicity (reduced water contact angle) and underwater superoleophobicity, achieving a high permeation flux of 361.5 L·m −2 ·h −1 and a separation efficiency exceeding 98.7% under optimized transmembrane pressure. Notably, it maintains a separation efficiency above 98% even after 10 consecutive reuse cycles. Under simulated solar irradiation, the membrane demonstrates exceptional photocatalytic self-cleaning capability, degrading multiple dyes (MB, RhB, MO) with an efficiency of 99.9% within 10 min while maintaining a flux recovery rate of 98.5%. This work presents a robust and sustainable strategy for treating complex oily wastewater through synergistic separation and advanced oxidation processes.

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.

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.

The development of aminated polysaccharide materials is often hampered by a low amine grafting efficiency and high energy consumption. Herein, we report a novel one-pot precipitation polymerization strategy for the facile and scalable synthesis of amine-modified glucose (AMG) by synergistically integrating three distinct reactions: the epoxy-amine addition for oligomer formation, the condensation cross-linking for constructing robust networks, and the Maillard reaction for dramatically enhancing amine grafting sites. This synergistic approach enables a high nitrogen content (18.0%) and a positive surface charge (+31.3 mV) in the resulting AMG. More importantly, the AMG exhibits a unique “hydrophilic and tert-butanol (TBA)-repellent” effect, which is mechanistically unraveled by a significant disparity in binding energy with water (−296.16 kcal/mol) versus TBA (−15.93 kcal/mol), as confirmed by molecular dynamics simulations. Through this effect, AMG successfully breaks the water-TBA azeotropic equilibrium that has been unreported, increasing the TBA concentration by 5% from that of its azeotrope via a simple distillation process. Furthermore, the obtained AMG demonstrates excellent and selective adsorption capacity for anionic dyes. This work provides a novel strategy for designing functional amino polysaccharides and develops a new technology for TBA azeotrope separation.
