- Abstract
Sn doped TiO2 nanocrystals were synthesized via a single-step hydrothermal method and the influences of Sn doping on TiO2 have been investigated. It is found that Sn doping not only facilitates the crystal transfer from anatase to rutile but also facilitates the morphology change from sphere to rod. The states of Sn were studied by XPS and the creation of oxygen vacancies by Sn doping is confirmed. Moreover, the HRTEM results suggest that Sn facilitates preferential growth of resulting nanocrystals along (110) axis, which results in the formation of rod-like rutile nanocrystals.
