[Preparation of Ce-loaded nano-TiO2 and study on its UV-Vis reflective spectrum].
Ce-loaded nano-TiO2 was prepared by the loading technology of metallic ions, and was characterized by XRD and TEM. The UV-Vis reflective spectra of nano-TiO2 and Ce-loaded nano-TiO2 were analyzed. The result shows that after loading rare earth element Ce the reflective spectral characteristic of nano-TiO2 moves to the visible region with a red shift to 500 nm, and the obvious change takes place in the absorbance in the visible spectral range with a three-fold enhancement. It is indicated that the load of rare earth element Ce is favorable to enhancing the absorption of visible and UV light of anatase nano-TiO2, and thereby greatly increases its photocatalytic activity.
