  • Patent number: 8389435
    Abstract: A metal oxide catalyst carrier particle has a center portion and an outer skin portion each containing a first metal oxide and a second metal oxide. The center portion and the outer skin portion are different in composition. The mole fraction of the metal of the first metal oxide is higher in the center portion than in the outer skin portion and the mole fraction of the metal of the second metal oxide is higher in the outer skin portion than in the center portion. The second metal oxide is selected from the group consisting of rare earth oxides, except for ceria, and alkali earth metal oxides. In addition, platinum is supported on the metal oxide catalyst carrier particle, thus forming an exhaust gas purification catalyst.
