La3+-doped TiO2 with different molar ratios of La/Ti(1/100,2/100,3/100,4/100 and 5/100) were prepared by a facile Sol-Gel method.The photocatalysts prepared were characterized by Brunauer-Emmet-Teller(BET) method,X-ray diffraction(XRD),UV-Vis diffuse reflectance spectra and surface photovoltage spectra(SPS).The results showed that TiO2 doped with 4%(the molar ratio of La/Ti) of La3+ had the highest photoinduced charge separation rate.The decolorizing performances of TiO2 and La3+-doped TiO2 was evaluated respectively by using aqueous methyl orange solution as simulative azo dye,and it could be concluded that the TiO2 doped with 4% of La3+ has the best photocatalytic performance.
