Abstract: The nanometer titanium dioxide surface modification of titanium dioxide industry production is the essential research works onTiO2 surface modif ication in China and foreign countries is reviewed in this paper. The types of modif-icat ion are divided into inorganic process and organic process. Nano-sized titania (TiO2) is an important inorganic function material,l which has wide application in many fields. It′s widespread application causes its surface modification technology becoming a hot spot of , surface modification is an important method to improve titania′s performances and to expand its application domain. In this paper, the aim and mechanism of TiO2modification were introduced. Introduces the different surface modification of nanosized titanium dioxide method ( modified inorganic and organic modification ) and application, finally describes the pure problems in the future research an
