Abstract:
Mesoporous, zirconium-based mixed oxides and a method of making the same comprises: injecting a polyvalent metal-containing solution into an electrolyte solution to form a mother liquor; forming a precipitate; aging the precipitate in the mother liquor to form the mixed oxides; washing the mixed oxides with an aqueous medium; drying and collecting the mixed oxides. The pH of the electrolyte solution exceeds the isoelectric point for zirconium-based mixed oxides. The mixed oxides exhibit a single particle size distribution, improved Ce02 reducibility in the presence of Rhodium, a decrease in surface area after calcination (800-1 100° C.) that is not more than 55%, and a tetragonal/cubic structure after calcination. After calcination at 1 100° C. for 10 hours in air, the mixed oxides exhibit a surface area >25 m2/g, a pore volume >0.20 cm3/g, an average pore size >30 nm, and an average crystallite size between 8-15 nm.

Claim (Index 2):
The method of  claim 1 , wherein the injection of the polyvalent metal-containing solution into the electrolyte solution occurs at pH from about pH(I)+2 up to about pH(I)+4 of the precipitate; wherein pH(I) is the pH at the isoelectric point for the zirconium-based mixed oxides.
