| Abstract: | PTA (peroxo titanic acid) gel was prepared by a modified sol-gel method from peroxo titanic acid using TiCl4/ethanol/water solution as the starting material at room temperature. Physicochemical properties of heat-treated gel were
characterized by IR, XRD, TG-DTA and SEM. Optimal preparing conditions were chosen to prepare anatase film for the photocatalytic
degradation of methyl orange. The dip-coating technique was used to synthesis the supported anatase film on quartz glass.
Photocatalytic efficiency for the degradation of methyl orange under UV irradiation was also examined. It was found that the
degradation efficiency of the anatase film synthesized in this paper is higher than commercial titania P25. |
