| 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. |
