Preparation of SiO2-TiO2 Films of High Photo-Catalytic Activity in the Electric Field Heating-Treatment
In this paper the Li+, Sb3+-doped SiO2-TiO2 thin films, which were heat-treated with an applied electric field, were prepared by sol-gel dip coating. The crystallization of the thin films in the electric field heating-treatment was studied by X-ray diffraction (XRD) and atomic force microscope (AFM). The photo-catalytic activity of SiO2-TiO2 films was studied under the condition of an electric field heating-treatment and mixing with some additive such as Li+ and Sb3+. Finally, studies on photo-catalytic degradation showed that the Li+, Sb3+-doped SiO2-TiO2 films on the quartz glass, of high photo-catalytic activity, were successfully obtained in the electric field heating-treatment.
