| Abstract: | This paper describes the preparation of TiO2 film photocatalyst fixed on the oxygen-diffusion film .The oxygendiffusion film was composed of oxygenadsorption layer and electrocatalyst layer. TiO2 film was fixed on the electrocatalyst layer. Examination of surface morphology of the TiO2 film was made using SEM.The rate of photocatalytic oxidation of oxalic acid on the TiO2 film was characterized by determining COD of the solution,The experiment results showed that the oxygendiffustion film played an important role in enhancing photocatalytic activity of the TiO2 film .The action of the oxygendiffusion film on TiO2 photocatalytic reaction was discussed. |
