Abstract: Provided is a composite of mixed metal oxides comprising by weight of the composite: alumina in an amount in the range of 1 to 50%; ceria in an amount in the range of 1 to 50% zirconia in an amount in the range of 10 to 70%; and one or more oxides of Group II elements in an amount in the range of 1 to 10%; optionally, one or more oxides Group III elements in an amount in the range of 0 to 20% is present. The mixed metal oxides may be effective integrated supports for precious metals used in emissions catalysts where a single component is an integration of alumina, ceria, zirconia, Group III metal oxides (dopants, e.g., La2O3, Y2O3, Nd2O3, Pr6O11), Group II metal oxides (additives, e.g., BaO, SrO, CaO, MgO), and optionally other transition metal oxides.
