| 发明名称 | Catalyst for purifying exhaust gas | ||
| 摘要 | Provided is a catalyst for purifying an exhaust gas, the catalyst excelling in catalytic performance and oxygen storage capacity. The catalyst for purifying an exhaust gas is a catalyst for purifying an exhaust gas which includes a ceria-zirconia composite oxide having a pyrochlore structure and a ceria-zirconia composite oxide having a cubic crystal structure, wherein at least a part of the ceria-zirconia composite oxide is composited with the ceria-zirconia composite oxide. | ||

| 主权项 | 1. A catalyst for purifying an exhaust gas comprising: an oxygen storing material which has a structure that a ceria-zirconia composite oxide (A) having a pyrochlore structure is partially or entirely coated with a ceria-zirconia composite oxide (B) having a fluorite type cubic crystal structure in a ratio of 50 to 100% relative to a surface area of the ceria-zirconia composite oxide (A). | ||
