The invention relates to a photocatalyst air sterilization disinfectant, which is specifically prepared by dissolving novel photocatalyst nano-particles with a core-shell structure, a small amount of sterilization and disinfection accelerant and a dispersing agent in water, wherein the novel photocatalyst structure is a core-shell double-layer nano-structure with the particle size of 0.05-10 microns, the core material is doped and modified nano-photocatalyst particles with the particle size of 0.005-1 micron, the shell material is a nano-porous layer with the mesoporous characteristic, and the thickness of the shell material is 0.05-5 microns. The air disinfectant can be directly sprayed in the air, has the characteristics of long-acting sterilization and disinfection, colorless products, no peculiar smell and harmlessness after being inhaled, and is suitable for sterilization and disinfection in the environments of airports, stations, offices, homes and the like. |
