摘要： Provided is an exhaust gas purification catalyst that combines reduction of pressure loss and enhancement of purification performance. This invention provides an exhaust gas purification catalyst 10 comprising a wall-flow-type substrate and first and second catalytic layers 261 and 262. The first catalytic layer 261 is provided to the interior of a partition wall 26, in contact with an entrance cell 24, from an exhaust inlet-side end 24a in the running direction, having a length L 1 less than L w . The second catalytic layer 262 is provided to the interior of a partition wall 26, in contact with an exit cell 25, from an exhaust outlet-side end 25a in the running direction, having a length L 2 less than L w . An internal portion of partition wall 26 in contact with entrance cell 24 has a substrate-exposing segment 26N 1 near the exhaust outlet-side end 25a.

摘要： Provided is a wall-flow-type exhaust gas purification catalyst with an oxygen storage material that has an increased OSC and exhibits its OSC without a compromise. This invention provides an exhaust gas purification catalyst 10 comprising a wall-flow-type substrate, a first catalytic layer 261 and a second catalytic layer 262. The first catalytic layer 261 is provided to an internal portion of a partition wall 26 in contact with an entrance cell 24. The second catalytic layer 262 is provided to an internal portion of a partition wall 26 in contact with an exit cell 25. Each of the first and second catalytic layers 261 and 262 comprises an oxygen storage material. The ratio (D 1 /D 2 ) of the coating density D 1 of the first catalytic layer 261 to the coating density D 2 of the second catalytic layer 262 is 1.1 to 1.8.
