Using nano-anatase TiO_2 powder and Ce(NO_3)_3 as raw materials Ce-loaded nano-TiO_2 was prepared by impregnating method, and characterized by XRD, TEM and UV-Vis spectrophotometer. The UV-Vis reflective spectra of nano-TiO_2 and Ce-loaded nano-TiO_2 were compared. The result shows that Ce-loaded nano-TiO_2 is still of anatase structure with Ce distributing uniformly on nano-TiO_2 surface. A red shift is observed in the UV-Vis adsorption spectrum with its mechanism being discussed.
