Abstract:
The present disclosure relates to methods of preparing sols of titanium dioxide nanoparticles that are photoactive, neutral, and in a substantially concentrated form. The methods particularly provide for concentrated sols in light of washing and dewatering under low cation concentrations and utilizing rapid peptizing through addition of the filter case to the peptizing agent. Concentrated acid may be utilized to maintain high TiO 2  concentration while still avoiding precipitation of the colloidal TiO 2 . Concentrated photoactive, neutral titanium dioxide sols are also provided as well as compositions thereof and photoactive coatings formed therewith.

Claim (Index 11):
The method according to  claim 1 , wherein the peptized alkaline titanium dioxide sol has a TiO 2  concentration of about 40% by weight or greater.
