The rare earth Yb doped TiO2 photo-catalysts TiO2-Yb were prepared by microwave hydrothermal method and its photo-catalytic activity under UV irradiation and solar irradiation were investigated. The optimal conditions for the preparation of TiO2-Yb photo-catalyst were obtained by optimizing the reaction condition. They were that Yb and Ti molar ratio n (Yb3+) /n (Ti4+) =0.14%, microwave power 600 W, reaction temperature 160â"ƒ, reaction time 3.5 h in parallel synthesis reaction and calcination temperature 650â"ƒ, calcination time 2.5 h in the high temperature box resistance furnace. The degradation rate of methyl orange was 98.71% when the TiO2-Yb was used for degradation of methyl orange in the UV irradiation for 50 min. But the degradation rate of methyl orange could almost reach 100% in the sunlight degradation of methyl orange for 4 h, which indicated that the TiO2-Yb prepared by microwave hydrothermal method had higher photo-catalytic activity.
