Preparation of Single-Phase and High Purity Nanophase TiO₂ by Microwave Hydrothermal Method

Abstract:

Preparation of single-phase and high purity nanophase TiO2 powders with small crystallite size were investigated by microwave hydrothermal method. By varying starting materials and reaction condition, four titania powders were prepared. Single-phase and high purity nanocrystalline anatase was obtained by hydrolysis of Ti(C4H9O)4 at 120oC for 3 h, which exhibited granulous and uniformly dispersed, with the average crystallite size of 10 nm. Well crystallized and single-phase rutile was obtained by hydrolysis of TiCl4 first at 120oC for 1.5 h and then at 180oC for 1 h, which exhibited shuttle-like and well-dispersed TiO2, with average diameter of 10 nm, by means of XRD and TEM.
