A New Preparation Method of Visible Light Responsive Titanium Diozide Photocatalytic Films by Sol-Gel Method

Two types of titanium dioxide sol solutions were prepared using titanium tetra-isopropoxide, urea, 2-methoxyethanol and water. The prepared sol solutions were dip-coated onto fused silica plates. These as-prepared films were dried at 100 ℃ and then annealed at 650 ℃. The annealed films were anatase type titanium dioxides. Visible light absorption by the films was observed in wavelengths longer than 400 run. Also, photodegradation of methylene blue by visible light irradiation was accelerated in the presence of the films prepared by these methods.
