The invention belongs to the technical field of environmental functional materials, and particularly relates to the application of a bismuth catalyst in the sterilization and disinfection of activated persulfate. Bismuth-based materials are used as catalysts to activate persulfate to generate a series of highly reactive reactive oxygen species (ROS), which attack pathogenic microorganisms in water to achieve excellent sterilization and disinfection effects; under visible light irradiation conditions, the disinfection efficiency can be further improved. . In addition, the bismuth catalyst is easy to obtain, the cost is low, the preparation method is simple, and it has strong catalytic activity and good stability. Disinfection by-products are produced; at the same time, after cyclic catalysis, the catalyst can still maintain a high catalytic activity, is easy to recover, and can be reused through regeneration, which is an environment-friendly material. |
