The development of adsorbents that combine high capacity with strong interference resistance remains a challenge for arsenic remediation in near-neutral industrial wastewater. Herein, we designed three functionalized MIL-101(Fe) composites – Si@Fe-MOF, L@Fe-MOF, and Fe/La-MOF – using silica incorporation, layered double hydroxide (LDH) assembly, and bimetallic synergy, respectively. This multi-faceted strategy aimed to overcome the inherent limitations of pristine MOFs, such as insufficient active sites. Under near-neutral conditions (pH = 7), the bimetallic Fe/La-MOF composite exhibited an exceptional adsorption capacity of 1708 mg/g for As(V), with a removal rate of 98.6%. Systematic characterization and modeling revealed that the adsorption process on all composites is governed by chemisorption. Mechanistically, the incorporated components enhance performance through distinct pathways: Si – OH groups provide additional binding sites, while La doping and Fe-La synergy create high-affinity bimetallic centers for selective arsenic complexation. This work provides a theoretical foundation and effective strategies for designing high-performance, stable adsorbents for treating arsenic in complex aquatic environments.

The efficacy of silane coupling agents in polymer nanocomposites is often restricted by limited reactive sites and insufficient physical engagement with the matrix. In this work, a multi-amino covalent organic framework-derived silane coupling agent (COF-SCA) was synthesized via a one-pot solvothermal method to engineer a stable filler–matrix interface. Unlike conventional small-molecule silanes, this macromolecular agent exhibits a porous, amino-rich framework. COF-SCA was applied to functionalize carbon nanotubes (CNTs) and hexagonal boron nitride (h-BN). Structural analysis indicates the formation of a continuous, rough coating on the nanofillers. Mechanical testing shows enhanced load-bearing capability, with tensile strength increases of 23% (CNTs) and 22% (h-BN) compared to APTES-treated systems. This enhancement is attributed to synergistic effects from abundant amino groups and the rigid porous framework.

In order to synthesise a fluorescent liquid crystal polymer (PL) with thermochromic effect at lower temperatures, allyl glycidyl ether (ME) was graft copolymerised with a fluorescent monomer (FM), a cholesteric monomer (M1), and a nematic monomer (M2) onto a polymethylhydrosiloxane (PMHS) backbone. This PL polymer was subsequently crosslinked with 4,4’-oxydianiline (MF), yielding a fluorescent liquid crystal elastomer (CPL) which exhibits a more ordered arrangement of the liquid-crystal molecules. The molecular structures and mesophase behaviours of the monomers and polymers were characterised by conventional methods, and all polymers were confirmed to meet the design requirements. The liquid-crystalline properties of the polymers before and after crosslinking were established as cholesteric phase by polarised optical microscopy (POM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), which also revealed excellent thermal stability, mesophase behaviour and thermal properties. Fluorescence spectroscopic analysis and imaging revealed that the polymer’s emission intensity is highly temperature-dependent. The cholesteric liquid crystal polymers exhibit different fluorescence intensities under UV irradiation at different temperatures, and the fluorescence is temperature-reversible. The two series polymer shows the expected dual effects of fluorescence and selective reflection at low temperatures, which have been fully verified experimentally.

A flexible polyionic liquid (PIL) nanofiber membrane-supported phosphomolybdic acid catalyst (PM-PIL) was fabricated via stepwise chemical transformation of polyacrylonitrile (PAN) nanofiber membranes. The nitrile groups of PAN were converted into pyridine units, followed by quaternization and anion exchange with phosphomolybdic acid (PMo), resulting in a polyionic liquid membrane with uniformly immobilized PMo species. Benefiting from its nanofibrous architecture and ionic liquid characteristics, the PM-PIL membrane simultaneously acts as a heterogeneous catalyst and a Pickering emulsion stabilizer, enabling efficient interfacial catalytic oxidation desulfurization. The PM-PIL membrane exhibited excellent catalytic performance toward dibenzothiophene (DBT) oxidation in an H2O2-based model oil system. Under optimized conditions (60 °C, O/S = 150:1), more than 90% DBT removal was achieved within 90 min, and complete desulfurization was obtained within 2 h. Compared with phosphomolybdic acid and poly(pyridine), the PM-PIL membrane showed markedly enhanced activity and stability, maintaining over 90% efficiency after six cycles. Product analysis confirmed selective oxidation of DBT to dibenzothiophene sulfone. This work provides a robust and recyclable membrane-based catalytic platform for efficient oxidative desulfurization.

Organolead halide coordination polymers have emerged as promising photocatalysts owing to their attractive photophysical properties and structural tunability. However, organolead bromides typically exhibit limited photocatalytic performance due to their generally narrow light absorption range and inefficient carrier mobility. To overcome these issues, we designed and synthesized a robust layered organolead bromide coordination polymer templated by the squaric acid ligand featuring short carbon chains and broad near-UV absorption. It achieves visible light absorption and high charge separation efficiency, in contrast to the two reported lead bromide analogues with large interlayer spacing. Upon exposure to AM 1.5G simulated sunlight, the hybrid bromoplumbate exhibits enhanced photocatalytic activity for CO2–CO conversion, with high product selectivity and cycling stability. Moreover, the photocatalytic CO2 reduction performance is further promoted by in situ incorporation of trace Ag nanocrystals as reductive cocatalysts for suppressing carrier recombination, prolonging charge lifetime, and reducing free energy for the *COOH key intermediate. This work underscores the critical role of coordination chemistry in modulating the relationship between the structure and property of crystalline materials.

To address the demands for efficient detection of combustible gas, such as hydrogen (H2), ethylene (C2H4), and acetylene (C2H2), in complex gas environments relevant to environmental monitoring, industrial safety, and smart homes, we developed zinc oxide (ZnO) gas sensors featuring bimetallic surface decoration with palladium (Pd) and gold (Au). Electron microscopy reveals the surface morphology of the sensing film and Pd/Au codecoration conformation, while X-ray photoelectron spectroscopy supports that codecoration modulates the distribution of surface oxygen species on ZnO. Gas sensing measurements demonstrate that Pd/Au decoration enhances both sensitivity and selectivity toward H2, C2H4, and C2H2. Specifically, a sensor decorated with 0.6 nm Pd and 2.3 nm Au exhibits a 178-fold increase in response to 160 ppm H2. Furthermore, by combining particle swarm optimization algorithm for feature selection with a support vector machine classifier, a recognition accuracy of 96.07% is achieved across seven different pure and mixture gas samples. This study presents a high-accuracy ZnO-based gas sensing platform optimized through both material engineering and machine learning algorithm, providing a reliable solution for real-world applications in industrial safety and environmental monitoring.

It is highly desired to develop continuous and scalable fabrication strategies for fibrous supercapacitors (FSCs) with helically structured electrodes, and the comprehensive performance, including long-term stability and operational safety, of the obtained devices is simultaneously desired to be optimized. In this work, we develop a one-step rotating microfluidic spinning technique for continuously preparing the CMC@MXene/PEDOT:PSS/CMC fibrous supercapacitor (CMC@MPC FSC) with helical structured electrodes and integrated electrode–electrolyte interfaces, which ensures the excellent ion migration capability, long-term stability, and operational safety of the obtained FSC. Therefore, the CMC@MPC FSC presents high energy storage capabilities including high volumetric capacitance (6.21 F cm–3), high energy density (3.35 mWh cm–3), high power density (50.01 mW cm–3), high rate capability (83.90% capacitance retention at 50 mA cm–3), and excellent electrochemical durability and stability, endowing it with great potential for wearable energy storage application, especially in the energy harvesting systems where high charge–discharge speed and frequency are required. This work presents a scalable, one-step approach for fabricating high-performance, all-in-one FSCs and lays the foundation for the next generation of flexible, integrated energy storage systems in smart textile technologies.

The Fenton-like application potential of MoS2 has recently attracted widespread interest in advanced oxidation processes. This study utilized natural molybdenite ore as the source of MoS2, and the Fenton-like reactivity of molybdenite was further enhanced by dropping Fe(III) ions on the basal planes of MoS2. EDS elemental analysis and XPS results suggest that Fe species were successfully anchored on the molybdenite surface, which exhibited exceptional efficiency in peracetic acid (PAA) activation. The Fe-molybdenite/PAA system achieved 83.2% degradation of sulfamethazine (SMT) within 30 min, and the reaction efficiency by Fe-molybdenite was 3.3 times higher than that of the unmodified molybdenite. HO• and Fe(V) were identified as the reactive species (RSs) during PAA activation, and SMT was degraded by these RSs. Increasing Fe-molybdenite and PAA dosages enhanced SMT degradation, with optimal performance observed at pH 4. Hydroxylation, nitrification, Smiles rearrangement and radical recombination reactions were involved during SMT degradation. Tetracyclines, dyes and other sulphonamide antibiotics could also be well degraded by Fe-molybdenite/PAA. This study elucidates fundamental design principles for engineering Fenton-like catalysts from natural mineral precursors.

The integration of multimodal sensors, energy harvesting, and storage modules facilitates the advancement of intelligent wearable electronic products. However, existing modular construction strategies have low integration levels, leading to cumbersome devices that may compromise the stability and reliability of signal acquisition. Here, we propose an all-in-one design strategy by integrating the three modules into a single polymer substrate prepared via laser-induced graphene technology to construct a fully integrated self-powered multimodal sensing system. This sensing system consists of bioenergy harvesting modules (lactate biofuel cells), flexible energy storage modules (Zn/MnO2 batteries), and multifunctional sensing modules (glucose, ascorbic acid, electrocardiogram, and electromyography). As a proof-of-concept application, the self-powered system is demonstrated to be worn on various parts of the human body for the real-time monitoring of health.

Nanofiber membrane separation technology is crucial in the field of oily wastewater treatment. However, conventional separation membranes typically focus solely on oil–water separation or the removal of a single pollutant, making it difficult to achieve efficient oil–water separation while simultaneously and effectively removing coexisting heavy metal ions. This limitation constrains their application potential for purifying complex industrial wastewater. To address the key bottlenecks of conventional membranes, namely low flux and poor antifouling performance, this study proposes a PVDF@MOF-303/PVDF@ZIF-67 (PMPZ) Janus composite membrane with dual-functionality for switchable oil/water separation and heavy metal adsorption. The membrane is constructed by forming a lipophilic/hydrophobic nanofibrous base layer of ZIF-67-modified PVDF@ZIF-67 (PZ) via electrospinning and seed-assisted growth, and subsequently creating a fluffy, superhydrophilic/underwater superoleophobic layer of MOF-303-loaded PVDF@MOF-303 (PM) via air-spray spinning and an in situ growth technique. These two distinct layers are then integrated through ultrasonic bonding to form the final bilayer Janus structure. The resulting PMPZ Janus membrane achieves mode switching by flipping its orientation, enabling gravity-driven separation of various oil/water mixtures and emulsions with high flux (oil flux up to 9500 ± 200 L m–2 h–1 , water flux up to 7400 ± 300 L m–2 h–1) and excellent separation efficiency (>99.3 ± 0.1%). More importantly, the PM layer of the composite membrane exhibits outstanding heavy metal adsorption capacity (e.g., for Cu2+ and Ni2+), achieving an adsorption efficiency reached 82.7 ± 0.5% when removing heavy metal ions from simulated oily wastewater. This composite membrane, which integrates efficient separation, switchable operation, and synchronous heavy metal removal, provides a highly promising solution for treating oily wastewater with complex compositions.

Developing a straightforward method for preparing superamphiphobic surfaces holds significant importance for both academia and industry. Despite considerable progress in superamphiphobic surface fabrication techniques, the time-consuming nature of the process and the difficulty in guaranteeing wettability performance mean that simple production of such surfaces remains a challenging task. This paper introduces a simple magnetron sputtering coupled with chemical deposition coating technique for constructing fractal floral structures on AZ91D magnesium alloy. These structures exhibit pronounced biomimetic characteristics and significantly enhance superamphiphobic property through expanded re-entry structures. Beyond demonstrating fostering chemical stability, this surface exhibits outstanding repellency toward rapeseed oil and ethylene glycol. The static contact angles of ethylene glycol, rapeseed oil, and n-hexane are 163.7°, 156.8°, and 152.5°, respectively. This approach for fabricating practical superamphiphobic surfaces offers distinct potential advantages through its low cost and high efficiency. Notably, the entire preparation process takes less than 30 min, presenting an alternative highly efficient approach for synthesizing superamphiphobic surfaces.

High entropy alloys (HEAs) have garnered considerable interest in catalysis owing to their unique characteristics, while transition metal oxides remain widely studied as classical catalysts. Herein, a novel core-shell FeCoNiCrCu/Fe 2 O 3 @C catalyst coated by a micro- and nano-scale amorphous carbon layer was prepared via a relatively facile synthesis method involving complexing multiple metal cations in organic solvents followed by calcination. Compared with MgH 2 , the initial hydrogen desorption temperature of MgH 2 with the FeCoNiCrCu/Fe 2 O 3 @C catalyst decreases significantly from 290 °C to 172 °C, and the peak temperature is reduced to 268 °C. Furthermore, the catalyzed MgH 2 enables hydrogen absorption even at room temperature under 3 MPa. It also demonstrates excellent cyclability, maintaining over 90% of its initial capacity after 50 cycles, along with progressively enhanced dehydrogenation kinetics. The excellent hydrogen storage performance of the catalyzed MgH 2 is contributed to the synergistic interplay of catalytic components collectively, including the “hydrogen diffusion channel” effect of the in-situ generated Co 3 Fe 7 , the “hydrogen pump effect” exhibited by the reversible catalytic phase pair Mg 2 Ni(Cu)/Mg 2 Ni(Cu)H 4 , as well as the multiphase interface composed of HEAs FeCoNiCrCu, Co 3 Fe 7 and MgH 2 . The amorphous carbon prevents particle agglomeration. This study demonstrates that the HEAs can exhibit significant catalytic effects through rational design.
