摘要：

With Ti(OBu)4 and Ce(NO3)3&middot6H2O as raw material, the pure and Ce doped TiO2 powder were prepared by a sol-gel method. The effect of dopping amount on the crystal transformation of TiO2 was studied. The results showed that the doped Ce hindered the process of phase transition of TiO2 particles from anatase to rutile, and propagated the temperature ranges of anatase. The crystallites growed larger with the increasing of the calcination temperature, and the crystal size became smaller with the doping increased. TiO2 particles were well dispersed in the state of anatase, with no agglomerates observed.
