| Abstract: | Ultrafine titania (TiO2) spherical powders have been prepared by controlled hydrolysis of titanium tetrabutoxide in presence of acetic acid/acetone solution. The powder X-ray diffraction shows that the as-dried precursor is crystalline in nature and shows broad peaks corresponding to hydrous titania (anatase) phase. The calcination of the hydrous titania precursor at 350°C/2hr under controlled conditions produces agglomerated spherical anatase titania powders (size 200nm) with improved crystallinity. These microporous agglomerates are found to be constituted of 14 nm primary anatase particles. These powders show high surface area (105 m2/g) as measured by BET technique. |
