| titleOfInvention | Exhaust gas purification catalyst and method for producing the same |
| abstract | To provide an exhaust gas purifying catalyst in which deterioration of cerium oxide or a cerium oxide-based composite oxide is suppressed even after durability, and a method for producing the same. The exhaust gas purifying catalyst comprises a refractory inorganic oxide in which a ceria-based composition is dispersed, and cerium oxide and at least one noble metal selected from the group consisting of platinum, palladium and rhodium. The dispersed ceria-based composition and the supported cerium oxide are in contact or bonded. The relative intensities of the (200) plane peak and the (311) plane peak with respect to the (111) plane peak of cerium oxide in X-ray diffraction are 0.45 to 0.5 and 0.35 to 0.4, respectively. This is a method for producing an exhaust gas purifying catalyst in which a refractory inorganic oxide in which a ceria-based composition is dispersed is further impregnated with cerium oxide by using a cerium solution having a concentration of 30 to 70%.
