| Abstract: | The preparation process of TiO2 sol using Ti ( OC4 H9 )4 as precursor was investigated . By the L16(44) orthogonal experiment method, four factors and their effects were studied,namely,the amount of water addes,the amount of C2H5OH added,the amount of CH3COOH added and the hydrolytic temperature on the Sol-Gel process. The photocatalytic activity of particles obtained was also analyzed. The orthogonal experiments yielded optimum preparation technology. And the stability of the sol prepared according to the optimum technology proved desirable. At the same time the particles obtained showed high photocatalytic activity. |
