| Abstract: | The sol-gel process was used to prepare nanostructured materials. With HAC as complexation and Ti(OBu)_4 as precursor in the start materials, TiO_2 gelation was obtained through hydrolyse and condensation process. Rare-earth Ce was introduced into the nanostructured TiO_2 to improve the photocatalystic capacity. The phase structure of the doped TiO_2 and their photocatalystic capacity were studied using DSC, XRD, TEM and optical adsorption etc. The optimum doping content and heat treatment temperature were chosen. |
