Solar For us humans, is an inexhaustible green energy , which is clean, large volume , as well as any place on Earth and other characteristics can be obtained . Since ancient times , people have a variety of different ways through the use of solar energy, such as solar heating , solar power and so on. However, even after a long development, human only in very small part of the solar energy to be utilized. It can be said , the field of solar energy related research work still has enormous potential. Photocatalytic reaction is a good method of using solar energy . In the photochemical reaction process , understood the importance of the photocatalyst . Titanium dioxide has good stability , low cost , photocatalytic activity, harmless , etc., is one of the best photocatalyst . In this paper, we successfully synthesized amorphous TiO 2 , with the reduction of nitrobenzene and phenol oxidation two reaction TiO 2 photocatalytic performance research, test results show that under UV irradiation , prepared TiO 2 showed some photocatalytic activity . The use of X-ray absorption fine structure spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS) identified amorphous TiO 2 formation and changes in the structure before and after reaction .
