Doped TiO2 Nanotubes: Synthesis and Application

Author(s): Guoliang Zhang, Xiaoxue Pan, Ling Wang, Xiping Sun, Linfei Yao, Zheng Fan.


TiO2 nanotubes have recently been studied extensively due to their high surface areas and finite length scales, allowing highly efficiency electron-hole charge separation and reduced recombination. Owing to these properties they can be used for instance in photocatalysis and lithium-ion batteries. The preparation of TiO2 nanotubes through hydrothermal process has received much attention. However, the practical application of TiO2 nanotubes is significantly hindered by their intrinsic energy band gap > 3 eV, which ensures that these materials cannot be excited by visible light. Visible-lightactivated TiO2 can be prepared by doping through incorporation or decoration with other metal ions, non-metal ions, and semiconductors. This review discusses various types of dopants, doping methods, and applications of doped TiO2 nanotubes.

Keywords: Doped TiO2, nanotubes, visible-light adsorption, hydrothermal treatment, photocatalysis.
