Abstract Nanometer titanium dioxide (nano-TiO2) has the advantages of good chemical stability, non-toxicity, long service life, low production cost and is an ideal photocatalyst material. The common nano-TiO2 preparation methods are first introduced. Then the modification methods of nano-TiO2, including doping modification and surface modification are discussed. The photocatalytic activity of nano-TiO2 in visible light can be greatly improved after modification. Finally, the application field of nano-TiO2 is introduced, and the development prospect of nano-TiO2 is prospected.
