Preparation of TiO_2 Films by Sol-gel

Cui Li-hu

Abstract

By using TiO2 powder and TiO2 sol, the TiO2 thin films were prepared on the substrate of aluminium alloy by sol-gel method in the paper.The photocatalytic properties of the TiO2 film made with two methods mentioned above are analyzed separately. The component and the distribution of phases of TiO2 film are characterized by XRD. The photocatalytic properties of the TiO2 film are characterized by the spectrophotometer. The results showed that the film made by TiO2 sol is better not only in crystallization but also in photocatalytic properties than that made by TiO2 powder.
