Synthesis and Characterization of Nanocrystalline Anatase by Microwave Hydrothermal Method

Abstract:

Uniform nanocrystalline pure anatase has been synthesized and characterized using tetrabutyl titanate aqueous solution as starting precursors by microwave hydrothermal method. The influences of synthesis conditions (reaction time and temperature) on the formation, crystal phase and crystallite size of TiO₂ has been investigated. A mixture solution of tetrabutyl titanate and normal butyl alcohol in 1:4 molar ratio is processed in a microwave hydrothermal autoclave at low temperature 120°C for different durations, at 200°C for 20 min to precipitate titania powders, respectively. It was revealed that uniformly dispersed and granulous single phase anatase prepared at 120°C for 180 min with the average particle size of 10 nm was formed by means of XRD and TEM.
