Abstract: Provided are catalyst composites whose catalytic material is effective to substantially simultaneously oxidize carbon monoxide and hydrocarbons and reduce nitrogen oxides. The catalyst composites have a two-metal layer on a carrier, the two-metal layer comprising a rhodium component supported by a first support comprising a refractory metal oxide component or a first ceria-zirconia composite; a palladium component supported by a second support comprising a second ceria-zirconia composite; one or more of a promoter, stabilizer, or binder; wherein the amount of the total of the first and second ceria-zirconia composites in the two-metal layer is equal to or greater than the amount of the refractory metal oxide component. Methods of making and using the same are also provided.

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.
