S-Scheme BaTiO3/TiO2 Heterojunctions: Piezophotocatalytic Degradation of Norfloxacin

•The catalyst is grown on a conductive glass, avoiding secondary contamination of the powder.•A new type of S-Scheme heterojunction, BaTiO3/TiO2, was prepared by a simple hydrothermal method.•The coupling of piezoelectric effect and photocatalysis significantly improves the performance of pollutant degradation.•The optimal catalysts have good degradation performance, general availability, and stability of degradation.
