| Abstract: | In this paper, anatase TiO2 nanoparticles are prepared by a simple precipitation method under 60℃, using titanium sulfate as Ti source. The product is characterized by XRD and Raman techniques. The results indicate that the product is Anatase TiO= nanoparticles with the diameter of 5.25nm. Its photocatalytic properties on cationic dye methylene blue are investigated. The results indicate that the photocatalytic time has great influence on the degradation of dye methylene blue. The degardation ratio of dye methylene blue reaches 57% after 6 h. |
