英文摘要：

TiO2 is a photocatalyst under ultraviolet light irradiation. It has a lot of application in photocatalysis field. Recently,with the development of nanomaterials sciences, mesoporous materials have been becoming the research highlight because of their special physics and chemistry properties. As a photocatalyst, mesoporous TiO2 presents a higher activity than conventional TiO2 in photodegradation of poison gases and organic dyes. The synthesis of mesoporous TiO2 and its application in photocatalysis has been reviewed in this paper.
