Microwave Hydrothermal Synthesis of Nanosize TiO₂

Abstract:

Nanocrystalline titanium dioxide was synthesized by microwave hydrothermal (MH) using tetrabutyl titanate and normal butyl alcohol as start materials. The mixture solution of tetrabutyl titanate and normal butyl alcohol in 1:1.5 molar ratio was processed in a microwave hydrothermal digestion system at 200oC for 20 min to prepare nanosized TiO2 powders. The results showed that the microwave assisted reactions proceed at a faster rate than the traditional hydrothermal methods. The powder was heat treated at 500oC and the final products is ~20 nm in size and well dispersed.
