Ultrafine Titanium Dioxide Doped Photocatalyst Preparation, Structure And Activity Of (¢ñ)

The paper uses Ticl3 as material to prepare ultrafme Ti02 photocatalyst by the means of sol-gel, and studies the influence on catalysic activity of heating temperature, surfactant, washing and drying condition,ect .work has been done to choose the best preparation condition and find a new way for catalysic applycation. The paper also studies mixing TiO2with A1203 and prepares ultrafme Ti02- A1203 photocatalyst. In the catalysic review ,the ultrafine TiC)2- A1203 in which Ti02 has irregular structrure possesses higher activity. It shows that the ultraflne TiO2-M~N has the prospect of application. At the same time ,the paper prepares the ultraflne Ti02-Eu203 and S0427 Ti02,and applies them into photocatalysis .In the end ,study has been done on the relation between structure and photocatalytic activity.
