Abstract: A series of TiO₂ catalysts supported on the tiles were prepared by a solution impregnation method. In order to improve the activity of catalyst, the dissolved transition metals or H₂O₂ were added in the aniline photodegradation reaction by TiO₂., whose Kinetics was simulated using GM (1,1) Model. The results indicated that the adding a little amount of Cu²⁺, Mn²⁺ or Co²⁺ can raise the photodegradation efficiency, and Ni²⁺ was just the opposite. Likewise, the adding of H₂O₂ can improve the activity of TiO₂, and it had the more obvious effects after interaction with Mn²⁺. When the reaction time was 50 min, the activity of TiO₂ was improved by19%～88% after the adding of Cu²⁺, Mn²⁺ or H₂O₂. It was also demonstrated that the kinetics of aniline photodegradation reaction by TiO₂ could be well simulated using GM (1, 1) model.
