【Abstract】 A glass supported TiO 2 thin film has been prepared by hydrothermal treating the mixed solution of Ti(SO 4) 2 and urea. Photocatalytic properties of the film were investigated by measuring the degradation of benzoic acid under UV light irradiation. It was found that the as obtained film showed good photocatalytic activity. The path of degradation was discussed.更多还原
