Preparation of spherical monodispersed ...

Spherical Titania (TiO2) with narrow size distribution and nice dispersibility has been obtained by hydrolysis in the mixed solvent of 1-propanol to de-ionized water under microwave assisted. The results show that the main effects on preparation of spherical TiO2 with small particle size, narrow size distribute and nice dispersibility include precursor concentration, microwave heating method and pH value. And microwave power is not obvious effect on the particle morphology and size distribution.
