Exhaust gas purifying catalyst |
摘要 |
An exhaust gas purifying catalyst is constituted by: noble metal particles (1); first compounds (2) which support the noble metal particles (1); second compounds (3) different in type from the first compounds (2); and oxides (4) which surround the noble metal particles (1), the first compounds (2) and the second compounds (3). A median diameter of the first compounds (2) and a median diameter of the second compounds (3) satisfy a relationship of a following inequality: median diameter of first compounds<median diameter of second compounds. |
