| Abstract: | This paper discusses preparation of nanometer-sized titanium dioxide by Sol-Gel method.In the Sol-Gel process,Ti(OC_4H_9)_4 is used as precursor,C_2H_5OH is used as solvent and CH_3COOH is used as chelating agent.By the experiment,four factors and their effects are studied,namely,the amount of water added,the amount of C_2H_5OH added,the amount of CH_3COOHadded and the temperature on the Sol-Gel process.The photocatalytic activity of particles obtained is also analyzed.With the results of XRD and TEM,the optimum preparation and the preparation reaction term are obtained. |
