【Abstract】 TiO2 powders were prepared by forced hydrolysis of boiling reflux conditions and with which photocatalytic degraded minim benzene in gas phase. The optimum conditions of the preparation of TiO 2 powders were ascertained through the experiments; The effects of carrier on photocatalytic activity of TiO 2 were examined. The results showed that the TiO 2 photocatalyst which was loaded by the carrier (such as actived carbon) with high activity of adsorption had the better effects on photocatalytic degradation.更多还原
