Abstract An ordinary-temp hydrolysis process for synthesizing nm-class rutile-type TiO2 with large specific surface area includes such steps as hydrolyzing TiCl4 as raw material to obtain precursor, and direct preparing said TiO2 by using beta-cyclodextrin (beta-CD), SiO2, Al2O3, or TiO2 of different crystal type as crystal seed. Its advantages are high productivity, low cost, large specific surface area and uniform sizes.
