Abstract: Described herein are methods for forming inorganic composite oxides. Such methods include combining, at a substantially constant pH of between about 5 and about 6.75 over a period of at least about 5 minutes, an acidic precursor composition and a basic composition to form a precipitate composition, wherein the acidic precursor composition comprises an alumina precursor, a ceria precursor, a zirconia precursor and optionally one or more dopant precursors; stabilizing the precipitate by increasing the pH of the precipitate composition to between about 8 and about 10; and calcining the stabilized precipitate to form an inorganic composite oxide. Also described are inorganic composite oxides formed using such methods.
