Facile one-step electrospinning of MoS2/PVDF nanofibrous films with enhanced piezo-photocatalytic activation of potassium peroxymonosulfate for efficient tetracycline degradation

A flexible MoS2 nanofibrous film was fabricated via one-step electrospinning for tetracycline hydrochloride (TC) removal. Radical quenching experiments revealed that •O2− and •SO4− were the dominant reactive species, and the degradation efficiency was approximately threefold higher than that achieved under light alone (≈80%). The enhanced performance arises from a piezoelectric-induced internal electric field that markedly facilitates the separation of photogenerated charge carriers, thereby accelerating potassium peroxymonosulfate activation and reactive radical generation. This study offers an effective strategy for designing flexible, low-energy-loss materials for aqueous pollutant remediation.
