The excessive use of ciprofloxacin, an antibiotic, has led to environmental challenges such as drug resistance and severe water pollution, necessitating effective mitigation strategies. Piezo-photocatalytic technology offers a sustainable solution. In this study, BiVO4, recognized for its exceptional visible light absorption conductivity, was embedded within polyvinylidene fluoride (PVDF) nanofibers address issues secondary pollution enhance material recovery. addition peroxymonosulfate (PMS) further improved the degradation process by generating highly reactive sulfate radicals (•SO4−), which acted synergistically with piezoelectric effects pollutant breakdown. Under combined stir, illumination, PMS activation, BiVO4 achieved 40% higher ciprofloxacin efficiency compared mechanical stir alone. This improvement is attributed generation polarization charges at both ends •SO4−, promoted efficient electron-hole separation oxidative degradation. study introduces novel approach piezo-photocatalytic treatment using flexible membrane materials enhancement.

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.
