  • EXHAUST GAS PURIFYING CATALYST
    Publication number: 20190193057
    Abstract: An exhaust gas purifying catalyst includes a catalyst layer formed inside a partition wall of a base material having a wall flow structure, and has an upstream-side and a downstream-side catalyst layer. The upstream-side catalyst layer includes Rh and a Ce-containing oxide, and the downstream-side catalyst layer includes Pd and a Ce-containing oxide. The mass of the catalyst layer per unit volume of the base material is from 105 g/L to 210 g/L, the mass of the upstream-side catalyst layer per unit volume in an upstream-side portion is from 50 g/L to 100 g/L, the mass of the downstream-side catalyst layer per unit volume in a downstream-side portion is from 100 g/L to 150 g/L, the Ce amount per unit volume of the base material is from 14 g/L to 35 g/L, and the Ce amount per unit volume in the upstream-side portion is from 5 g/L to 20 g/L.
