【Abstract】 urface photocatalytic technology is widely used in surface self-cleaning, sewage treatment, water to hydrogen conversion and other fields. In particular, composite semiconductor materials, using the p-n junction principle, greatly improve the concentration of surface electrons and holes, thereby improving the ability to absorb sunlight, leading to broad application prospects. This paper focuses on the progress of nano-photocatalytic technology in the field of sewage treatment, water-hydrogen conversion and surface modification of medical devices, as well as the application prospects in antimicrobial self-cleaning for food packaging, transportation equipment and building materials. This is important to reduce the current cross-infection of contact in public places and to control the global epidemic.更多还原
