Abstract

The phenomenological model of sulphate anions effect on the nanodispersed titania synthesis during hydrolysis of titanium tetrachloride was studied. It was proposed that both chelating and bridging bidentate complexes formation between sulphate anions and octahedrally coordinated [Ti(OH)_h(OH₂)_6-h]^(4-h)+ mononers is the determinative factor for anatase phase nucleation.
