Microwave-assisted Synthesis of Rutile Titania Nanoparticles from TiOCl2 Aqueous Solution

Abstract

Abstract: Rutile TiO2 nanoparticles of controled size were prepared by a very simple forced hydrolysis from TiOCl2 aqueous solution using microwave irradiation. The products were analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The TiO2 particles produced from the present route have spherical structure. The influence of heating power on TiOCl2 solution hydrolytic process was studied and a possible nucleation mechanism of rutile TiO2 nanoparticles was discussed.
