Oxygen Vacancy Enhanced Photocatalytic Performance Towards Marine Microorganisms Inactivation over Ag/Bi 2 O 3

In this study, Bi2O3-OV with different concentrations of oxygen vacancies was prepared by reduction method, Ag NPs were loaded onto pure Bi2O3 and Bi2O3-OV by photodeposition. The effect of different electronic structures of the carrier on the performance and reaction mechanism of the Ag-loaded catalysts was also emphasized. The results showed that the sterilization rate of pure Bi2O3 was only 49.56
