Boosting piezo-photocatalytic performance in antibiotic wastewater treatment through graphitic carbon nitride–zinc oxide based heterojunction engineering

This work constructed a g-C 3 N 4 –ZnO@PVDF film to boost piezo-photocatalysis. PVDF piezofield suppresses electron-hole recombination, while the g-C 3 N 4 –ZnO heterojunction guides directional electron transport, achieving 99.15% tetracycline degradation.
