Generally, photocatalysis can be applied to get energy economically, synthesize the useful materials, and remove environmentally harmful materials by transforming solar energy to chemical energy. Recently, the availability of photocatalysis has largely interested in the environment of Ubiquitous. Therefore, the study for photocatalysis has progressed by many investigators in domestic. In this study, titania sol was prepared by the sol-gel proess and characteristics of the products was investigated by TGA, XRD and SEM.
