A novel method for preparing a titania dispersion by blending two different titania dispersions synthesized by a solvothermal process and a hydrolysis process. The titania dispersion has a plurality of titania particles substantially uniformly dispersed therein and can be blended to provide a high concentration of titania with an anatase crystalline structure to provide the desired level of photocatalytic activity. The present invention also permits the preparation of transparent titania dispersions. The solution may be used for various decontamination and clean energy generation applications.
