Abstract

Photocatalytic activity of doping TiO2 with different kinds of ions were investigated. Through photocatalytic degradation of methylene blue solution, photocatalytic activities of the three materials after treatment and the influencing factors were compared. The result showed that the degradation rate of methylene blue by using La3+ doped TiO2 or thiourea doped TiO2 is higher than Fe3+ doped TiO2. Compared with 45wt% thiourea in optimum condition, 0.5wt% La3+ addition have the same effect. After that, the study focus on La3+ doped TiO2. The absorption intensity and particle size of undoped TiO2 and La3+ doped TiO2 were investigated, the result showed that absorption intensity of 0.5wt% La3+ doped TiO2 have a high absorption in the visible region, UV region and have fine uniform particles with a narrow size distribution and less aggregate.
