Nano-TiO2 is a kind of functional material for photocatalysis application with high efficiency and energy saving. Nowadays, its preparation and application have attracted more and more attention. The developing features and shortages of nano-TiO2 are reviewed in this paper. In particular, the technology and characteristics for the preparation of nano-TiO2 by liquid phase process are specially introduced. It is emphasized that the photocatalysis technique of nano-TiO2 has wide applications in environmental protection field. Finally, the development direction of nano-TiO2 is pointed out. In addition, the advantages and shortages of TiO2 photocatalysis technology in the practical applications are also discussed. Meantime, the de velopment prospect of photocatalysis technology is also forecasted.
