Laminated TiO2/Fe2O3/ITO and TiO2/Fe2O3/glass films acting under visible light irradiation were prepared by sol-gel processing as well as TiO2/V2O5/ITO or TiO2/WO3/ITO films. Under Xenon lamp irradiation, the rate of bleaching of Methylene Blue (M.B.) on TiO2/Fe2O3/ITO or TiO2/WO3/ITO was found to become greater than that of the original TiO2/glass which was the best under black light irradiation. The TiO2/Fe2O3/glass, whose Fe2O3 was confirmed to be formed as α-hematite by using Mossbauer measurement, seems to be applicable because of its photocatalytic ability.
