Abstract: | Nano titanium dioxide, a new kind of inorganic material, exhibits many properties different from the block materials due to its nanoseale particle size. The properties of non-toxic, chemical stability, super hydrophilism and its thermal stability?, nonirritant make it outstanding semiconductor photocatalyst. It's of great significance to prepare nano-titania with relatively high?photocatalytic activity. This paper provides a review on the recent progress in nano-titania preparation,the methods of which including Physical methods, Chemical methods, Physical- Chemical methods. The advantages and disadvantages of each method are analyzed, and prospects for future development and main research in nano-titania preparation are proposed. |
