AbstractTiO2 photocatalytic thin films prepared by microarc oxidation (MAO) were modified by adding some oxides into electrolytes. The results show that the photocatalytic degradation ratio of the TiO2 film can be improved with the doped components of V, Ag and Ce, while the semiconductor doping may also obviously improve the photocatalytic activity of the film. As the doped concentrations of V2O5 and SnO2 are 0.5 and 1.0 mmol/L, respectively, the photocatalytic degradation ratio is significantly improved. XRD analysis results reveal that the above doping does not change the lattice type of TiO2. Doped films formed on Ti substate have high content of anatase, which would be ideal for the film with high photocatalytic properties. SEM images of the films indicate that the above doping makes the thickness and surface area of the film increase, and the microarc channel diameter of the film decrease.
