EXHAUST GAS PURIFYING CATALYST

摘要

The present invention provides an exhaust gas purifying catalyst that can keep high catalytic performance even being subjected to exhaust gas. The exhaust gas purifying catalyst includes: noble metal particles (7); and supports (3), each support supporting the noble metal particles (7), wherein at least a certain amount of the noble metal particles (7) is provided on an outermost surface of the support (3), or provided within a range of 10% inside of a diameter of the support (3) from the outermost surface in a direction toward a center of the support.
