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.
