Abstract ：
In this study, the coupling agent polydopamine/polyethyleneimine (PDA/PEI) was utilized to modify the surface of an alpha-Al2O3 support. Owing to the cross-linking characteristics of the -NH2 and -OH functional groups with Zn2+ ions on the support by the coupling agent, a continuous and dense 2D-zeolitic imidazolate framework-8 (ZIF-8) membrane was induced and regulated. The hydrogen (H-2) separation performance, mechanism and preparation optimization of the ZIF-8 membrane grown on the modified layer of PDA/PEI were investigated. The results indicated that a ZIF-8 membrane with an approximate thickness of 12 mu m formed on a Zn2+@PDA/PEImodified alpha-Al2O3 support. The H-2 permeance of the ZIF-8 membrane was 3.02 x 10(-7) mol.Pa-1.m(-2).s(-1) at 25 degrees C and 0.15 MPa, with ideal selectivities of 12, 51, and 59 for H-2/CO2, H-2/N-2, and H-2/CH4, respectively. Notably, these values significantly exceeded the Robeson upper limits. The primary mechanism of zinc ion complexation in the PDA/PEI codeposit layer involves the formation of complexes between the O and N atoms on the layer and Zn2+, and a significant number of imines (NH=) can be employed to chelate Zn2+ and facilitate the formation of Zn =N compounds. This facilitated the heterogeneous nucleation of ZIF-8 on the support surface, resulting in the synthesis of continuous ZIF-8 membranes with ultrahigh H-2/N-2 and H-2/CH4 selectivity and excellent intergrowth.

Abstract ：
Para-arsanilic acid (p-ASA) is widely used as a feed additive, making it a pervasive environmental pollutant. Due to its migratory and transformative nature, p-ASA can easily convert into more toxic inorganic arsenic during its migration, thereby increasing the ecological burden and posing a threat to human health. Efficient removal of p- ASA from water is crucial for mitigating arsenic contamination. Efficient removal of p-ASA from water is crucial for mitigating arsenic contamination. This study introduced zirconium-loaded collagen fiber membrane (CFM-Zr), a novel, sustainable membrane adsorption material synthesized by retanning collagen fiber membranes (CFM) with zirconium (Zr). Leveraging the physicochemical properties of CFM and the strong affinity of Zr forp-ASA, CFM-Zr achieved highly efficient p-ASA removal. The resulting membrane was made entirely from green, low-carbon and recyclable raw materials, achieving sustainable removal of p-ASA while realizing the concept of treating waste with waste for environmental recovery. Remarkably, the retanning with zirconium significantly enhanced the Zeta potential of CFM-Zr, strengthening its electrostatic attraction to p-ASA, with a maximum adsorption capacity of 289.02 mg & sdot;g- 1, which was 19.72 times higher than that of the CFM before retanning (13.95 mg & sdot;g-1). Its adsorption rate constant was 12.54 mg & sdot;g-1 & sdot;min- 1. Moreover, CFM-Zr showed good reusability and exhibited electrostatic adsorption and metal coordination effects on the "organic" parts (-OH,-NH2) and "inorganic" parts (As-O) of p-ASA, effectively removing it. This work provided a promising bio-based material for water purification, promoted the sustainable utilization of leather industry waste, and offered significant advancements in environmental remediation and resource recovery.

Abstract ：
Lignin-containing cellulose nanofibers prepared from sugarcane bagasse was used as the substrate to fabricate the superhydrophobic membrane for oil-water separation. The superhydrophobic membrane with a water contact angle of 159.5 degrees was obtained by a facile dipping method based on triclorocadadecylsilane (OTS). The lignin retained in the membrane not only enhanced the hydrophobicity of the membrane, but also contributed to the performance of oil-water separation. When the content of lignin reached 17.53 %, the separation efficiencies of the membrane for diesel and dichloromethane could reach 96 % and 86 %, respectively. Meanwhile, the membrane also showed good oil separation flux up to 716.4 L/(m2 & sdot;h) for dichloromethane, and good recyclability, presenting a promising oil adsorbent in oil spill recovery and environmental protection.

Abstract ：
The development of high-performance hydrogen separation membranes is a crucial step in the advancement of sustainable energy technologies and the achievement of carbon neutrality. In this study, zeolitic imidazolate framework-8 (ZIF-8) membranes with an ultra-high selectivity for hydrogen over carbon dioxide were successfully synthesised on polydopamine/3-aminopropyltriethoxysilane (PDA/APTES) modified Al2O3 supports. The interfacial layer exhibited excellent adhesion and a high density of functional groups, which served as nucleation sites for the growth of ZIF-8 crystals. The resulting membranes exhibited a dense and defect-free structure, achieved through an optimised 12 h in-situ growth process. The membranes exhibited excellent gas separation performance, with hydrogen(H2) permeance reaching 14 × 10−7 mol·Pa−1·m−2·s−1 and ideal selectivities of 20.3, 22.1, and 26.8 for H2/CO2, H2/N2 and H2/CH4, respectively, at 25 °C and 0.2 MPa. In comparison with the ZIF-8 membrane that was synthesised on a pure PDA modified layer, the H2 permeance increased by 14.8 %. Notably, the selectivity for H2/CO2 increased by almost threefold. Moreover, long-term stability tests demonstrated the durability and robustness of the ZIF-8 membranes under operational conditions. © 2025 Elsevier Ltd

Abstract ：
Detecting trace endocrine disruptors in water is crucial for evaluating the water quality. In this work, a innovative modified polyacrylonitrile@cyanuric chloride-triphenylphosphine nanofiber membrane (PAN@CC-TPS) was prepared by in situ growing triazine porous organic polymers on the polyacrylonitrile (PAN) nanofibers, and used in the dispersive solid phase extraction (DSPE) to enrich trace nitrobenzene phenols (NPs) in water. The resluted PAN@CC-TPS nanofiber membrane consisted of numerous PAN nanofibers cover with CC-TPS solid spheres (similar to 2.50 mu m) and owned abundant functional groups, excellent enrichment performance and good stability. In addition, the method based on PAN@CC-TPS displayed outstanding capacity in detecting the trace nitrobenzene phenols, with 0.50-1.00 mu g/L of the quantification, 0.10-0.80 mu g/L of the detection limit, 85.35-113.55 % of the recovery efficiency, and 98.08-103.02 of the enrichment factor, which was comparable to most materials. Meanwhile, when PAN@CC-TPS was adopted in the real water samples (sea water and river water), the high enrichment factors and recovery percentages strongly confirmed the feasibility of PAN@CC-TPS for enriching and detecting the trace NPs. Besides, the related mechanism of extracting NPs on PAN@CC-TPS mainly involved the synergistic effect of hydrogen bonding, pi-pi stacking and hydrophobic effect.

Abstract ：
Humic acid (HA) is the main precursor of carcinogenic compounds such as trichloromethane, which form during the disinfection of drinking water. Therefore, removing HA from water sources is crucial for producing safe drinking water. This study introduces a novel approach using dilute nitric acid as a nitrogen source to dope pristine Ti3AlC2 (TAC) to varying degrees, enhancing the material's photocatalytic degradation performance for HA. Characterisations through X-ray diffraction, Fourier transform infrared, scanning electron microscopy, UV-vis and X-ray photoelectron spectroscopy revealed that the surface morphology of the modified catalyst changed from an original blocky lamellar structure to a rod-like cluster structure, which is advantageous for light trapping. In addition, the incorporation of nitrogen reduced the band gap of the material from 1.25 to 1.15 eV, considerably enhancing its overall light responsiveness and thereby improving its photocatalytic performance. The results demonstrated that the photocatalytic degradation efficiency of HA by TAC under optimal conditions reached 93.8 %, which is 4.3 times higher than the 21.8 % efficiency achieved using the undoped TAC material. The enhanced photocatalytic activity is attributed to N doping, which not only reduces the TiO2 band gap at the TAC surface but also improves the electrochemical behaviour of TAC. This results in enhanced light response and more efficient separation of photogenerated electron-hole pairs. The mechanism for CTAC-N-x photocatalytic degradation of HA was investigated using trapping agent experiments, revealing that the primary active substance responsible for the degradation is O-2(-).

Abstract ：
Separating anionic surfactant-stabilized oil-in-water emulsions remains a critical challenge due to the presence of surfactants. In this study, we developed a unique collagen fiber-based CFM-PEI-TiO2 with superhydrophilic and underwater superoleophobic properties, enabling efficient separation of various anionic surfactant-stabilized oilin-water microemulsions and nanoemulsions through charge demulsification effects. The membrane achieved high separation flux (1458.50 L & sdot;m- 2 & sdot;h- 1) and separation efficiency (99.94%) simultaneously. Importantly, the membrane exhibited remarkable mechanical durability, as it remained capable of separating diverse oil-in-water emulsions even after being subjected to abrasion with sandpaper for 500 cycles, highlighting its long-term durability and economic viability. The robust membrane also demonstrated excellent recyclability, with a separation efficiency of over 99% after twelve cycles and a flux of 1299.10 L & sdot;m- 2 & sdot;h- 1 after fifteen cycles. These properties can be attributed to the PEI-induced electrostatic interactions and the enhanced superhydrophilicsuperoleophobic interaction provided by TiO2 on the unique collagen fiber membrane. The outcomes emphasize the versatility and potential of our membrane in overcoming the challenges associated with emulsified oily wastewater.

Abstract ：
Two-dimensional Cu/TACN rod-spherical photocatalysts were prepared via dilute nitric acid etching with MAX Ti3AlC2 (TAC) via a solvothermal method. These Cu/TACN photocatalysts were designed for photocatalytic hydrogen production in water. Notably, the 8 %Cu/TACN photocatalyst exhibited superior performance, achieving a hydrogen production rate of 2235.1 mu mol center dot g-1 center dot h-1, which was about 21 times greater than the value of 109.0 mu mol center dot g-1 center dot h-1 observed for pure TAC. The marked enhancement in performance is attributed primarily to the synergistic effect of the close interfacial contact and aligned energy levels between the highly conductive, rod-like TACN and Cu/Cu2O particles. This interaction significantly accelerates the separation and transfer of photogenerated carriers. Consequently, etched and modified TAC treated with dilute nitric acid and a transition metal (Cu) provides a novel approach for designing photocatalysts and optimizing energy applications.

Abstract ：
A boron and iron co-doped biochar (B-Fe/biochar) from Masson pine bark was fabricated and used to activate peroxydisulfate (PDS) for the degradation of guaiacol (GL). The roles of the dopants and the contribution of the radical and non-radical oxidations were investigated. The results showed that the doping of boron and iron significantly improved the catalytic activity of the biochar catalyst with a GL removal efficiency of 98.30% within 30 min. The degradation of the GL mainly occurred through the generation of hydroxyl radicals (center dot OHs) and electron transfer on the biochar surface, and a non-radical degradation pathway dominated by direct electron transfer was proposed. Recycling the B-Fe/biochar showed low metal leaching from the catalyst and satisfactory long-term stability and reusability, providing potential insights into the use of metal and non-metal co-doped biochar catalysts for PDS activation.
