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 herein is a barium sulfate-containing catalyst carrier. The catalyst carrier is useful for supporting an exhaust gas purification catalyst, such as a three way conversion catalyst. In an embodiment, the carrier comprises BaSO4/thermally stable alumina. Further provided is a process for preparing the catalyst carrier, with or without precious metals, comprising treating a barium oxide/alumina or barium carbonate/alumina with a stoichiometric amount of sulfuric acid (H2SO4), thus forming BaSO4/alumina in situ in good yield and at low cost.
