Deskripsi
We have proposed and experimentally tested a phenomenological model of SO<sub>4</sub><sup>2-</sup> sulphate anions effect on the titania nucleation during hydrolysis of titanium tetrachloride. Sulphate anions form the chelating bidentate complexes with primary [Ti(OH)<sub>h</sub>(OH<sub>2</sub>)<sub>6-h</sub>]<sup>(4-h)+</sup> with the influence on the next olation process and promotion of anatase phase nucleation.
