| Abstract: | Using Sol-Gel method, the photocatalysts of powder type TiO2 were prepared from tetrabutyl titanate and activity evaluation for photocatalytic decomposition of methyl orange. The influence of concentration of reaction, ageing time, reaction temperature, calclning temperature and calclning time on photocatalytic activity were investigated. The result shows good photocatalytic properties. |
