The results indicate that the film possesses porous structure. Photocatalytic activity of the film is higher than that prepared simply through sol gel method and varies with the film thickness and diameter of TiO 2 particles. Furthermore, the activity is improved when Pt was loaded on the film by photoelectrochemical method.展开更多
