Claim 0:
1. A process for preparing a titanium-silicon complex, the process comprising:
(1) contacting a silicon compound with water and an acid or a base in a solvent to form a first solution containing a partially-hydrolyzed silicon material, wherein a molar ratio of water to silicon is in a range from about 0.2:1 to about 0.8:1, a weight ratio of the acid or the base to the solvent is from about 1:2000 to about 1:20, and the silicon compound comprises a silicon alkoxide; and
(2) contacting a titanium compound with the first solution containing the partially-hydrolyzed silicon material at a molar ratio of titanium to silicon from about 0.3:1 to about 0.9:1 to form a second solution containing the titanium-silicon complex.
