Abstract

An aqueous dispersion of titanium oxide comprising a chloride ion and at least one br φ nsted base other than chloride ion, preferably at least one br φ nsted base selected from a nitrate ion and a phosphate ion. Preferably, the titanium oxide contained in the aqueous dispersion is predominantly comprised of a Brookite type titanium oxide. The aqueous titanium oxide dispersion is prepared by hydrolyzing titanium tetrachloride in the presence of at least one br φ nsted base. A titanium oxide film formed from the aqueous titanium oxide dispersion has excellent photocatalytic activity, transparency, and adhesion to a substrate.
