Abstract: With anatase nano-TiO2 and Ce(NO3)3 as raw materials, the nano-Ce/TiO2 inorganic antibacterial agent have been prepared by impregnation method. The antibacterial activities was evaluated with the halo method and the antibacterial mechanism was studied. The results show that the nano-Ce/TiO2 inorganic antibacterial agent has outstanding antibacterial activities and the antibacterial mechanism is of rare earth cerium ion dissolving.
