Microwave Hydrothermal Preparation of Uniform Nanocrystalline Anatase
The synthesis of nanocrystalline pure anatase at low temperature and short time is not an easy achievement, as the synthetic processes generally lead to amorphous, moreover some processes normally require harsh reaction. Uniform nanocrystalline pure anatase has been obtained using tetrabutyl titanate and normal butyl alcohol under microwave irradiation condition at low temperature 120 °C for 3 h. This process simplication will lower production cost and make continuous process possible. It was revealed that the as-synthesized TiO2 products without any heat treatment were uniformly dispersed and granulous single-phase anatase, with the average grain size of 10 nm, by means of XRD and TEM.
