DUAN Zhigang, ZHU Zhongqi, NA Wei, ZHANG Jin, LIU Qingju(Department of Material Science and Engineering ,Yunnan University ,Kunming 650091)  
TiO_2 powders doping with different content of CeO_2 are prepared by Sol-gel method. The effects of doping proportion on the crystal structure, absorption spectrum and photocatalytic degradation of methylene are studied.The results indicate that the absorbing wavelength threshold value of TiO_2 samples doping with different CeO_2 content is about 500nm. The rate of degradation of methylene of the sample is higher than that of Degause P25 after 4h irradiation by fluorescent lamp.The optimal content of CeO_2 is 7%(mol).
