Abstract

Tio2 heterogeneous photocatalytic energy can realize many reactions which are difficult or impossible to achieve under normal conditions under mild conditions. Various methods for preparing nano TIO2 are introduced by gas phase method and liquid phase method. The hydroprecipitation method and the sol-gel method are introduced, and the supercritical fluid drying method and its advantages are described. The mechanism of photocatalytic reaction and the influencing factors of catalytic activity are introduced. The photocatalytic activity of Tio2 as photocatalyst is used. The application of inorganic and organic degradation in protection, anti-virus sterilization in health care, and organic synthesis have also been elaborated; future research work is expected.
