METHOD FOR PRODUCING HIGHLY ACTIVE PHOTOCATALYTIC TITANIMU OXIDE

摘要

PROBLEM TO BE SOLVED: To improve the efficiency of a titanium oxide photocatalyst without adding a transition metal or the like that is conventionally carried out for improving the efficiency of the photcatalyst. SOLUTION: The method for producing a photocatalytic titanium dioxide comprises forming TiO2with a thickness of 100-200 nm on a substrate and then partially forming Ti2O3by evaporation on the TiO2film so as to improve the photocatalytic activity of TiO2. Also, the method for producing the photocatalytic titanium dioxide may comprise forming TiO2by laser evaporation at a substrate temperature of 400-600°C in oxygen-containing atmosphere and then depositing Ti2O3by vacuum evaporation.
