Glyphosate is a persistent herbicide that contaminates water and poses health risks, yet conventional removal methods remain limited. Photocatalysis offers a promising alternative but is hindered by issues such as charge recombination, poor light utilization, and the formation of phosphate (PO 4 3- ) by-products. In this study, a coupled system is constructed, comprising ZnIn 2 S 4 nanocage (ZIS-HNCs)/BiOCl mesoporous single-crystal nanosheet (BiOCl MSCN) heterojunction–photocatalytic optical and Fe-modified zeolite fibers, to completely remove glyphosate from aqueous environments. Light radiated from the hollow optical fibers excites the ZIS-HNCs/BiOCl MSCN photocatalyst to generate electron–hole pairs. The formation of a heterojunction between ZIS-HNCs and BiOCl MSCN accelerates interfacial charge transfer, increases the production of holes and electrons, and consequently enhances their performance in degrading glyphosate. PO 4 3- produced from photocatalytic degradation is removed in situ by the Fe-modified zeolite fibers through Fe–O–P coordination and electrostatic adsorption. This suppresses the quenching of photogenerated electron–hole pairs by PO 4 3- , further enhancing the efficiency of glyphosate degradation and inhibiting the formation of phosphate by-products. The photocatalysis–ion adsorption coupling strategy provides a novel and effective approach for the simultaneous removal of pesticide residues from aquatic environments.

Vacancy-ordered double perovskites have emerged as promising candidates for single-component white light-emitting diodes (WLEDs) owing to their intrinsic broadband emission, dopant-induced color tunability, and stable optoelectronic properties. However, their practical application is limited by the difficulty of obtaining high-quality crystals, as the typically rapid and poorly controlled crystallization processes tend to induce lattice disorder and defect formation. In this work, we report a 4-mercaptobenzoic acid (4MBA)-assisted coprecipitation strategy to synthesize high-quality 3%Sb 3+ -doped Cs 2 ZrCl 6 (CZC:3%Sb (4MBA)) microcrystals (MCs). Despite its non-coordinating nature with the crystal surface, 4MBA functions as an effective kinetic regulator that retards crystallization and enhances growth control, thereby suppressing lattice disorder and defect formation to improve crystal quality. As a result, the optimized CZC:3%Sb (4MBA) MCs achieve a photoluminescence quantum yield (PLQY) of 88%, twice that of the unmodified MCs, while concurrently ensuring excellent ambient and thermal stability. Fabricated WLEDs based on CZC:3%Sb (4MBA) MCs exhibit warm white emission with a high color rendering index (CRI) of 94 and maintain stable operation over 14 h. This work presents an effective strategy for regulating crystal growth to enhance the optical performance of lead-free vacancy-ordered double perovskites, paving the way for high-performance, single-component WLEDs.

In this study, a novel gas sensor based on iron (Fe) - cobalt (Co) bimetallic metal-organic framework (MOF) was synthesized and applied to the detection of trimethylamine (TMA) for the first time. The sensing mechanism was elucidated through density functional theory (DFT) calculations. Experimental results demonstrate that the introduction of Fe 3+ into the Co-MOF (Fe/Co-MOF) not only increased its specific surface area and the number of oxygen vacancies but also enhanced the intrinsic conductivity and carrier mobility of Co-MOF, which improves the response ability for TMA detection. The response value and response/recovery time of Fe/Co-MOF to 100 ppm TMA were 164.18 and 8 s/3 s, and the minimum detectable concentration was 1 ppm at room temperature. DFT calculations revealed that the introduction of Fe 3+ will enhance the charge transfer ability of Co-MOF, making its D-band center closer to the Fermi level, thereby enhancing the electron density and reactivity of metallic active sites. By introducing Fe 3+ into Co-MOF, not only will more oxygen vacancies be generated, but also it will combine with Co 2+ to form a Fe-O-Co channel structure, thereby effectively enhancing the electronic transmission ability of the Co-MOF. The design of the Fe/Co-MOF structure has solved the problem of low conductivity of Co-MOF and has successfully been applied to the detection of TMA for the first time, providing a new strategy for the application of MOFs materials in gas detection.

The peroxodisulfate (PDS)-based oxidation systems are promising for Cu(II) complex decomplexation owing to its capacity to harness the self-enhanced decomplexation (SED) effect of Cu(II) complexes. This phenomenon was conventionally attributed to liquid-phase autocatalysis via Fenton-like reactions between daughter Cu(II) species and PDS. However, this frequently adopted hypothesis is inconsistent with the actual catalytic activity of Cu(II) species and has been challenged by our preliminary results. Herein, we revisit the decomplexation of copper(II)-ethylenediaminetetraacetate (Cu(II)-EDTA) in UV/PDS system, with particular emphasis on correcting the catalytic behaviors of Cu species and clarifying the indispensable role of UV-irradiation in SED effect. Both acidic and alkaline conditions exhibit significant SED effect, but we reveal a pH-dependent SED mechanism that is fundamentally different from the prevailing liquid-phase autocatalysis mechanism. Under acidic conditions, Cu(II) complexes exhibit enhanced catalytic capacity with decreasing ligand coordination strength, primarily stemming from the activation of PDS by Cu(I) species produced via the irradiation-induced intramolecular charge transfer; In alkaline environments, only liberated Cu(II) substantially contribute to SED effect via spontaneous hydrolysis, forming nanostructured CuO after aging, which activates PDS through heterogeneous Fenton-like processes. While acidic conditions demonstrate faster decomplexation, alkaline-generated solid products facilitate multi-cycle treatment efficiency and alkaline conditions also exhibits stronger resistance to chloride. This work corrects the misinterpretation of SED mechanism in UV/PDS/Cu(II)-EDTA system, and provides a fundamental and accurate mechanistic basis for the efficient treatment of copper-containing organic wastewater by PDS-based processes.

A MOF-based dual-network fibrous membrane is prepared via one-step electrospinning. • The membrane exhibits excellent superhydrophobicity and self-cleaning function. • Structure–performance relationship of fiber size effect and filtration is revealed. • Excellent iodine aerosol removal efficiency is preserved under elevated humidity. The efficient remediation of radioactive iodine aerosols is crucial for nuclear pollution control. However, existing technologies struggle to simultaneously capture radioactive iodine vapors and aerosols while maintaining performance under high-humidity conditions. Herein, a facile and scalable one-step electrospinning strategy is used to fabricate a superhydrophobic dual-network MOF-based composite fibrous membrane (ZIF-8@PVP/MK). The hierarchical dual-network structure construction and tunable fiber diameters are achieved by regulating spinning voltage. An organosilicon resin rich in low-surface-energy Si–CH 3 groups is used to ensure superhydrophobicity. Through in-situ blending, ZIF-8 nanoparticles are embedded within and on the fibers, significantly increasing the purification performance for radioiodine aerosols with iodine adsorption capacity of 1981 mg/g and high filtration efficiency over 99%. Spectroscopic analysis reveals that the C O bonds in PVP and the C N bonds in ZIF-8 ligands provide electrons for iodine capture, facilitating charge transfer and strong chemisorption. Moreover, ZIF-8 loading creates abundant surface defects and enhances roughness, providing numerous active sites and pathways for aerosol capture. Notably, the superhydrophobic membrane exhibits excellent self-cleaning capability and water resistance, ensuring long-term stability and recyclability. This work presents a promising material for the efficient purification of radioactive iodine aerosols and offers a practical strategy for nuclear waste management in high-humidity environments.

One-step flax degumming and simultaneous bleaching were achieved by TA-PDS. • High degumming efficiency was obtained while fiber properties were preserved. • Selective lignin degradation was promoted by electrophilic •OH. • Wastewater loads, water footprint, and life-cycle burdens were reduced. In this study, a thermal-alkaline activated peroxydisulfate (TA-PDS) process with integrated degumming and bleaching functions was developed for flax fiber treatment. Under the optimized conditions of a NaOH/PDS molar ratio of 6:1, a PDS concentration of 8.8 g/L, and a reaction time of 2.7 h, the residual gum content of the treated fibers was as low as 5.8%, while the fiber retained a tenacity of 2.1 cN/dtex, a whiteness of 48.7%, and a fiber yield of 75.0%. Compared with the traditional alkaline degumming process, TA-PDS achieved more effective removal of non-cellulosic components while preserving favorable fiber properties. Mechanistic investigation demonstrated that radical oxidation and alkaline hydrolysis played synergistic roles in lignin degradation, with electrophilic •OH acting as the dominant oxidative species. The preferential attack of •OH on the electron-rich structures of lignin, together with OH⁻-promoted cleavage of β-O-4 ether linkages, contributed to selective lignin removal and preservation of fiber integrity. Environmental assessment further demonstrated that TA-PDS reduced water consumption from 45.0 to 15.0 m 3 per ton of raw flax and lowered the global warming potential from 766.2 to 285.4 kg CO₂ eq, together with reductions in wastewater pollutant load, and overall environmental burdens. These findings indicate that TA-PDS provides a feasible strategy for simultaneously achieving efficient degumming and favorable fiber properties while improving the environmental sustainability of the process.

Photocatalytic hydrogen production from methanol suffers from the sluggish reaction kinetics and low photocatalytic selectivity, as well as the inaccessible on-demand hydrogen production due to the intermittent nature of solar energy. Here, we present a polyoxometalates (POMs)-mediated strategy, acting as photocatalysts and electron-coupled-proton buffers, which not only yields value-added formaldehyde products with high selectivity of almost 100%, but also enables the spatiotemporally decoupled hydrogen production. The photo-reduced POMs exhibit an ultra-low onset oxidation potential (<0 V vs. NHE), thus enabling the direct photocatalytic hydrogen production from methanol in the presence of POMs and Pt/C catalysts with the hydrogen evolution rates of 0.431 mmol h −1 mg −1 Pt and 0.407 mmol h −1 mg −1 Pt in the H 4 SiW 12 O 40 -based and H 6 ZnW 12 O 40 -based systems, respectively. Moreover, an “indirect” methanol fuel cell based on the POM-mediated system can be constructed with an open-circuit voltage of ∼0.9 V and a maximum power density of 33 mW cm −2 .

Fossil solvent is replaced with edible vegetable oil in interfacial polymerization. • Soya-bean oil is optimal due to its well film-forming ability and low viscosity. • Soya-bean oil-based NF membrane exhibits thick PA layer with high salt rejection. • Soya-bean oil can act as green substitute for greener TFC membrane production. Despite the prevalent use as organic phase in interfacial polymerization (IP), conventional fossil solvents such as n-hexane are toxic, volatile and flammable, raising growing concerns about their safety. Regarding this issue, hereon we employ edible vegetable oils as a green organic phase to replace fossil solvents for the preparation of thin film composite (TFC) nanofiltration (NF) membranes. Five candidates including soya-bean oil, peanut oil, corn oil, flaxseed oil and olive oil were selected for exploration. Characterization demonstrates that soya-bean oil is the optimal selection, which can be attributed to its superior film-forming ability, low viscosity and facile removability. The selectivity of the soya-bean oil-based TFC NF membrane can be further improved by regulating IP parameters. Compared to the membranes fabricated with n-hexane and Isopar G, the soya-bean oil-based NF membrane exhibits a much thicker polyamide (PA) layer with thickness around 161 nm. This structural characteristic enables excellent desalination performance, with salt rejection exceeding 98% for MgSO 4 and 99% for Na 2 SO 4 . However, the increased thickness also results in a relatively lower water permeability of about 3.5 L m −2 h −1 bar −1 . Our study demonstrates the feasibility of using soya-bean oil as a substitute for conventional fossil solvents in IP reaction. It thereby offers a promising alternative for enabling greener production processes in TFC NF membrane manufacturing. Download: Download high-res image (180KB) Download: Download full-size image

Superhydrophobic sponge materials offer a promising solution for treating oily wastewater. To address the challenges of hydrophobic modifier leaching and process complexity, this study developed a composite sponge by immobilizing hydrophobically modified mesoporous silica nanoparticles (H-DMNH) onto a polydopamine (PDA)-modified melamine sponge (MS) framework. Hydrophobic long-chain siloxanes were grafted onto the mesoporous silica nanoparticles (DMNH) via hydrothermal synthesis, and the resulting H-DMNH was firmly anchored onto the PDA coated MS sponge through electrostatic interactions, hydrogen bonding, and hydrophobic interactions. The obtained H-DMNH/PDA@MS sponge exhibits integrated and durable superhydrophobicity with a water contact angle (WCA) of 154°, antifouling properties, high oil absorption capacity (36.2–118 g/g), efficient separation of oil/water mixtures and emulsions (>97%), and good recyclability. Under simulated solar irradiation, the H-DMNH/PDA@MS sponge surface temperature rapidly rises to 65 °C within 1 min, achieving a photothermal conversion ability of 88.3%, thereby promoting adsorption through reducing oil viscosity. Furthermore, the H-DMNH/PDA@MS sponge shows certain flame-retardant characteristics (loss rate is 25.6%), which substantially enhance operational safety in flammable environments. With this multifunctional attribute, the H-DMNH/PDA@MS sponge emerges as a robust and sustainable material for practical oil-water separation applications.

Macrophage-based immunotherapy holds great promise for solid tumors but is limited by impaired phagocytosis and unstable M1-type polarization due to immunosuppressive tumor microenvironments. Here, we develop engineered macrophages by conjugating oncolytic adenovirus (OA)-loaded zeolitic imidazolate framework-8 (ZIF-8) onto macrophage surfaces via bioorthogonal chemistry (ZIFOA-M). This platform leverages localized viral delivery to selectively downregulate “don't eat me” signals (CD47 and CD24) on tumor cells, thereby restoring macrophage phagocytic capacity. Moreover, viral replication within tumors induces immunogenic cell death, releasing major damage-associated molecular patterns (DAMPs) that sustain M1-type polarization and promote durable antitumor immunity. ZIFOA-M also enhances tumor antigen presentation, eliciting robust tumor-specific T cell responses. Our strategy integrates phagocytosis restoration, microenvironment remodeling, and adaptive immune activation in a single, localized platform. ZIFOA-M offers a complementary and translatable approach to overcome key barriers in macrophage-based cancer immunotherapy.

Achieving high activity and stability while reducing Pt loading remains a major challenge in developing cathode oxygen reduction reaction (ORR) catalysts for H 2 /air fuel cell. Here, a novel low-Pt intermetallic nitride catalyst (PtFe 3 N) consisting of a strained Pt shell and an antiperovskite-type PtFe 3 N core on a confinement-effect carbon support are synthesized via an initial impregnation-co-reduction strategy. The MEA with PtFe 3 N/DMC as cathode yields a current density of 1370 mA cm −2 at 0.6 V and maximum power density of 0.92 W cm −2 , significantly outperforming that of Pt/C benchmark (1170 mA cm −2 and 0.79 W cm −2 ). Besides, the PtFe 3 N/DMC enabled MEA has a lower performance decay rate (1.9%) compared to the MEA with Pt/C (48.2%). EXAFS, XPS and DFT calculations jointly support that the cooperative strain effects induced by Fe and N endows PtFe 3 N with an optimal Pt d-band center position and accelerated kinetics. Furthermore, the introduction of N elements promoted the strong metal-N interactions, which effectively suppress Fe dissolution and significantly improve the ORR durability under operating conditions. This work provides a novel strategy for low-Pt intermetallic to enhance the corrosion resistance of 3d transition metals and to improve the ORR activity.

The global spread of harmful algal blooms (HABs) has become a serious environmental problem, which urgently needs innovative control methods. This study explored the suppression efficiency of copper- and zinc-based metal-organic frameworks (MOFs) on growth and toxin production of the toxigenic microalga Alexandrium minutum . The physical characterization data confirmed that Cu-MOF has a higher surface area (1207 m 2 g −1 ) than Zn-MOF (56.9 m 2 g −1 ). Both materials could inhibit the growth of A. minutum with a concentration-dependent pattern. Comparatively, the Cu-MOF resulted in notable inhibition even at low concentrations. However, Zn-MOF stimulated growth at low concentrations but showed an inhibitory effect at higher doses (≥5 mg L −1 ). Both MOFs caused oxidative stress, alteration of cell membrane, and photosynthesis disruption. Additionally, transcriptomic findings revealed a major change of nutrient metabolism. Genes related to phosphorus uptake were mostly up-regulated, while those for nitrogen assimilation were largely down-regulated. The decrease in medium phosphorus and change in nitrogen levels also reflected this transcriptional response and demonstrated the imbalance in nutrient ratio. Furthermore, both MOFs, specifically at elevated concentrations, reduced overall production of paralytic shellfish toxins (GTX1, GTX4, GTX2 and GTX3). This study showed the potential utility of MOFs as targeted porous materials for HAB mitigation.
