Synthesis of Phase Controlled TiO2 Nanocrystals

Abstract:

Article Preview

Synthesis of TiO2 nanocrystals directly from the TiO2 micron powders by the hydrothermal method is reported for the first time. A new route of preparing amorphous TiO2 nanopowders is demonstrated in this paper. The TiO2 nanocrystals phase structure can be controlled by the subsequent treatment with different concentration HCl solutions. When the amorphous TiO2 nanopowders are treated with 0.2M HCl aqueous solution, a spherical anatase phase nanorystals are obtained, while treated with 1.0M HCl aqueous solution, a rod-like rutile phase nanocrystals are formed.
