| Abstract: | Nanocrystaline TiO 2 was prepared with the sol-gel method.Its crystalline phase and particle size were determined by XRD and SEM .The granularity and its distributing for the products were analyzed by laser granularity. In our research, the effects of some factors such as the amount of TiO 2 used, the initial concentration and pH value of the solution containing Methyl blueness ,and the amount of H 2O 2 used on TiO 2 photocatalysis for degrading methyl blueness were investigated. |
