Abstract:
In an exhaust gas purifying catalyst according to the present invention, a substrate includes inflow-side cells, outflow-side cells, and porous partition walls, each partition wall separating the inflow-side cell from the outflow-side cell. Catalyst portions include: 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 second catalyst portions, each second catalyst portion being provided on a surface of the partition wall that faces the outflow-side cell on a downstream side, and the exhaust gas purifying catalyst satisfies the following expressions:IB1/IA×100≥60%, IB2/IA×100≥60%, IC1/IA×100≥3%, and IC2/IA×100≥3%, where IA, IB1, IB2, IC1, and IC2 represent pore volumes, definitions of which can be found in the specification.
