A method of forming inorganic composite oxides is described herein. Such a method comprises contacting an acidic precursor composition and a basic composition comprising an alumina precursor, a ceria precursor, a zirconia precursor and optionally one or more dopant precursors at a substantially constant pH of from about 5 to about 6.75 over a period of at least about 5 minutes Forming a precipitation composition in combination; Stabilizing the precipitate by increasing the pH of the precipitation composition from about 8 to about 10; And firing the stabilized precipitate to form an inorganic composite oxide. Further, an inorganic composite oxide formed by using such a method is described. |
