A ratio (RhZrXO/RhZrCeNdO) of a mass of the catalyst powder (B) to a total mass of the catalyst powder (A) and the catalyst powder (B) may be set in the range of 1 to 50%. Further, the catalyst powder (B) may consist of a composite oxide which contains Zr as a primary component, a rare-earth metal except Ce, and Rh. The exhaust gas purifying catalyst of the present invention can provide enhanced exhaust gas conversion efficiency.

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.
