摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning catalyst which can suppress the deterioration of cerium oxide and a cerium oxide-based composite oxide after endurance running and a manufacturing method thereof. SOLUTION: The exhaust gas cleaning catalyst is made by carrying at least one noble metal selected from the group consisting or cerium oxide, platinum, palladium, and rhodium, on a refractory inorganic oxide in which a ceria-based composition is dispersed. The dispersed ceria-based composition and the carried cerium oxide are contacted or linked with each other. In an X-ray diffraction of cerium oxide, the relative intensity of a (200) plane peak and that of a (311) plane peak to a (111) plane peak are 0.45-0.5 and 0.35-0.4 respectively. Additionally, the refractory inorganic oxide in which the ceria-based composition is dispersed is impregnated and carried with cerium oxide by using 30-70% cerium solution. COPYRIGHT: (C)2004,JPO
