Abstract
There is provided an exhaust gas purifying catalyst including a substrate and catalyst portions. The substrate includes an inflow-side cells, outflow-side cells, and porous partition walls, each partition wall separating the inflow-side cell from the outflow-side cell. The catalyst portion includes: (group A) first catalyst portions, each first catalyst portion being provided on a surface of the partition wall that faces the inflow-side cell on an upstream side in an exhaust gas flow direction; and (group B) second catalyst portions being provided on a surface of the partition wall that faces the outflow-side cell on a downstream side in the exhaust gas flow direction. Each catalyst portion of one of group A and group B includes at least one oxidizing catalyst layer and at least one reducing catalyst layer, and each catalyst portion of the other of group A and group B includes at least one oxidizing catalyst layer and/or at least one reducing catalyst layer.
