Photocatalyst antibacterial principle: After being exposed to visible light, photocatalysts generate a large number of active superoxide ion and hydroxyl radicals. They can easily penetrate the cell wall of bacteria, destroy the cell membrane, enter the bacteria, prevent the transmission of film-forming substances, and prevent Disconnect its respiratory system and electronic transmission system, thereby effectively killing bacteria. The bactericidal rate of SAT NANO photocatalyst antibacterial agent is more than 99.98%, and it can kill more than 600 kinds of bacteria such as Staphylococcus, E. coli, Aspergillus niger and so on. Widely used in hospitals, schools, food factories, homes.


Here is the test result from the third party, you can find that it is very good for photocatalytic and antibacterial,
