Pt/TiO2 was prepared by impregnation method and characterized with XRD、 BET and XRD results showed TiO2 as prepared was anatase and the average particle sizewas about17 nm.The results of the photocatalytic degradation of 3-methyl indole suggested that the influences of Pt amount and loading amount of catalytics have obvious effect to catalyst activity.The concentration of flow rate and consistence obviously influenced the 3-methyl indole photocatalytic degradation.
