Abstract Amid increasing fossil energy scarcity, a key solution is using solar to split water into hydrogen (H 2 ). However, single photocatalysts face limitations of low utilization rate and rapid carrier recombination, so constructing novel composite promising solution. Here, ZnO/UiO‐66‐NH @ZnIn S 4 (ZUN@ZIS) catalyst with twin S‐scheme heterojunction constructed for the first time, in which ZnIn (ZIS) nanosheets are grown situ on surface (ZUN) rhombic octahedra. Under irradiation visible light without help any co‐catalyst, H evolution prepared ZUN@ZIS‐20 5.05 mmol g −1 h , 3.7, 2.1 46 times higher than that ZIS, UiO‐66‐NH /ZIS (UN/ZIS) ZUN, respectively. Moreover, synergistic effect resulting ZUN@ZIS facilitates provision efficient channels carrier/mass transfer ensures structural stability. Various experimental characterizations theoretical calculations confirm by ZUN ZIS can facilitate easy separation photogenerated carriers. This study has developed new idea multi‐heterojunction photocatalysts, provided valuable reference development photocatalysis technology.

In this study, an ionic liquid–ethanol interface strategy is proposed to synthesize NH2-MIL-101(Fe) nanocrystals at room temperature. The as-synthesized exhibit small crystal sizes, abundant ligand defects, and unsaturated metal sites. present superior catalytic activity for the cycloaddition reaction of CO2 mild conditions (room temperature 1 bar pressure), much higher than NH2-MIL-101 (Fe) microcrystals synthesized by conventional solvothermal method. conversion propylene oxide catalyzed achieves a 99% yield within 2.5 h, accompanied generation rate carbonate production per gram catalyst (Rcarbonate) 52.8 mmol g–1 h–1. contrast, system employing shows lower 19.28% 10.28 were further used treatment simulated industrial flue gas with volume ratio N2/CO2 = 85:15. results show efficient ambient pressure, even relatively low concentrations. This work not only offers facile, energy-consumed, environmentally benign method fabrication MOF nanostructures but also provides high-performance systems fixation separation.

Biodegradable Cellulose Acetate Nanofibrous Membranes with Self-Sustaining Electrostatic Effect for Efficient and Stable Air Purification

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Март 28, 2025

Amid the global pursuit of carbon neutrality and pressing challenge severe air pollution, degradable cellulose acetate (CA) materials hold great potential in field filtration. However, their weak polarity poor antibacterial properties limit widespread application this field. Herein, we developed CA-based nanofibrous membranes (CAPZ NFMs) with antimicrobial properties, which achieved efficient stable filtration performance through a self-sustaining electrostatic effect driven by polarity. CAPZ NFMs were fabricated electrospinning solution that contained CA, highly polar zwitterionic copolymers (PSG), biocompatible Zr4+. The groups PSG increased to 19.62 mN·m-1, significantly surpassing pristine CA (2.94 mN·m-1). This enhancement granted surface 2.07 kV, enabled PM0.3 efficiency 99.56% while maintaining low pressure drop 79 Pa. Notably, maintained superior under high humidity conditions 6 months outdoor storage. Additionally, Zr4+ coordinated form quaternary ammonium groups, endowing broad-spectrum efficacy over 99.99%. work could provide new strategies for developing next-generation biodegradable, high-electrostatic materials.
