Abstract

Cerium doped anatase titania powders were prepared by sol-gel process, with ammonium (IV) nitrate and Titanium (IV) butoxide as the raw materials. The characteristics of anatase $TiO_2$ and cerium doped $TiO_2$ were investigated by XRD, DTA, FE-SEM and UV/Vis spectroscopy. Research results indicated that XRD data characteristic diffraction peaks of anatase phase and also showed that cerium phase was not observed. Moreover XRD and DTA results imply that the addition of cerium to titania modifies the mechanism of formation of the titania phases.
