    摘要： The present invention is intended to ensure the improvement in catalytic performance of an exhaust gas catalytic converter, which is an essential performance thereof, ensure the thermal resistance thereof and downsize the converter, i.e., improve the arrangeability thereof. The exhaust gas catalytic converter has an upstream catalyst and a downstream catalyst which are arranged in upstream and downstream sides of an engine exhaust passage through which exhaust gas flows. Each of the upstream catalyst and the downstream catalyst contains an oxygen storage component. The oxygen storage component in the upstream catalyst has a structure in which Rh atoms are placed at or between crystal lattice points of a mixed oxide containing Ce and Zr and has a larger amount of oxygen storage than the oxygen storage component in the downstream catalyst under the same temperature conditions.

    摘要： Disclosed is an exhaust gas purifying catalyst, which comprises an oxygen absorbing material having a catalytic noble metal arranged at a lattice position or an interlattice position of a crystal structure of a composite oxide containing Ce and Zr, which is capable of sufficiently exhibiting a catalytic function even if a ZrO2 mass ratio is out of the range of 20 to 30 mass % or 65 to 90 mass %. Specifically, in an exhaust gas purifying catalyst formed with a catalyst layer including a cerium-zirconium (CeZr) composite oxide, the composite oxide contains ceria (CeO2) and zirconia (ZrO2) in such a manner that a mass ratio of ceria to a total mass of ceria and zirconia falls within the range of 36 to 64 mass %. Further, the composite oxide contains, in the form of an oxide, a rare-earth metal other than cerium (Ce), in the range of 3 to 20 mass % with respect to a total mass of the composite oxide.
