摘要： PROBLEM TO BE SOLVED: To provide a promotor material for purifying automobile exhaust gas having high oxygen storage capability at a comparatively low temperature, capable of purifying the exhaust gas at high efficiency from a state at a comparatively low temperature by a carried catalytic active substance.SOLUTION: Since a solid solution ratio K of ceria 16c and zirconia 16a is 30-90%, an oxygen release peak temperature of a ceria-zirconia material 16 is lower in comparison with, for example, a uniform conventional solid solution type in which ceria 16c and zirconia 16a are uniformly solid-solved, to thereby heighten oxygen storage capability at a comparatively low temperature. The ceria-zirconia material 16 has a core-shell structure in which the core is formed of zirconia 16a, and ceria-zirconia 16d and ceria 16c exist on the surface of the core. Since the surface of the ceria-zirconia material 16 has cerium-rich property, very high activity can be obtained when carrying platinum 14, to thereby enable highly efficient purification of exhaust gas from a state at a comparatively low temperature.
