Abstract：To solve the problem of current photocatalysis with low catalytic efficiency, the immobilized loading of titanium dioxide was carried out on glass sheet, fiber membrane and steel wire mesh by solgel method and leaching technique. The effects of preparation and catalytic process on the catalytic degradation of titanium dioxide were analyzed with methylene blue as target pollutants. The results show that with the increasing of dip coating number, the photocatalytic degradation efficiency of methylene blue on the surface of titanium dioxide is increased with latter stability. The decreasing sequence of removal rate is glass sheet, fiber membrane and steel mesh, and the best numbers of film coating are 3,4 and 4, respectively. The photocatalytic degradation efficiency of titanium dioxide prepared by glass coating for 4 times is the highest, and the degradation rate for 4 h UV can reach 75.3%.
