Abstract: A catalyst for purification of exhaust gas containing a phosphorus compound includes: a lower catalyst layer containing at least one of noble metal provided on a refractory three-dimensional structure; and an upper catalyst layer at an inflow side of exhaust gas and an upper catalyst layer at an outflow side of exhaust gas provided on a surface of the lower catalyst layer. The upper catalyst layer at the inflow side and the upper catalyst layer at the outflow side have different concentrations of noble metal. The catalyst has an intermediate zone with a length of 3 to 23% of the overall length of the refractory three-dimensional structure provided between the upper catalyst layer at the inflow side and the upper catalyst layer at the outflow side. The intermediate zone starts from a position 10 to 38% from an end face of the catalyst at the inflow side of exhaust gas.

Abstract: 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 comprising a wall-flow-type substrate and first and second catalytic layers. The first catalytic layer is provided to the interior of a partition wall, in contact with an entrance cell, from an exhaust inlet-side end in the running direction, having a length L1 less than Lw. The second catalytic layer is provided to the interior of a partition wall, in contact with an exit cell, from an exhaust outlet-side end in the running direction, having a length L2 less than Lw. An internal portion of partition wall in contact with entrance cell has a substrate-exposing segment near the exhaust outlet-side end.
