- Abstract
Titanium dioxide nanoparticles have been prepared by hydrolysis of titanium isopropoxide. An aqueous solution with varied pH and peptizing the resultant suspension was used to prepare TiO2 nanopowder with a narrow size distribution. The synthesized powder was examined by X-ray diffraction, scanning electron microscope and transmission electron microscope. The as-prepared powder entirely consisted of anatase crystalline phase with a particle size of 7.6 nm. Only powder obtained from the solution of pH = 2 had a fine particle size with spherical morphology. The anatase to rutile transformation occurred at the temperatures lower than 600 °C.
