Abstract

In this work, rutile Sn-doped TiO₂ nanocrystals are synthesized by hydrothermal method, with TiCl₄ and SnCl₄ aqueous solutions serve as the precursors. When the TiCl₄ and SnCl₄·5H₂O serve as precursors with ratio of Ti⁴⁺/Sn⁴⁺ 4:1, most of the Synthesized crystals are square morphology, with diameter of 30nm. When the ratio of Ti⁴⁺/Sn⁴⁺ changed to about 1:1, the obtained samples display various kinds of morphology. Some of them are tiny square crystals with the size less than 20nm. The bigger ones is about 100-120nm in length and 30-50nm in diameter. And the aspect ratio is about 3:1. When the ratio of Ti⁴⁺/Sn⁴⁺ is 0:1, the crystals is 20nm in diameter, and 30-120nm in length. The results indicate that combination of Ti⁴⁺ and Sn⁴⁺ has relative evident effect on the crystals morphology. The component of the obtained samples has been analyzed by X-ray energy dispersive spectroscopy (EDS). The result shows that the highest atomic percent concentration of the doped-Sn is very low. The experiments results indicate that it is hard for other metal ions to dope into the rutile TiO₂ by the way of lattice-substitute.
