  • Publication number: 20220016601
    Abstract: An exhaust-gas purification apparatus includes: a honeycomb base material including a plurality of exhaust-gas flow paths partitioned by a porous wall; and one or more catalyst noble metals carried by the honeycomb base material. The catalyst noble metals are selected from the group consisting of platinum, palladium, and rhodium. The honeycomb base material has a noble metal concentrated surface section in which a 50%-by-mass noble metal carry depth for a specific noble metal that is one type among one or two catalyst noble metals is less than 50% of the distance from the surface to the center of the inside of the porous wall. The 50%-by-mass noble metal carry depth is the depth at which, when the amount of the specific noble metal carried between the surface and the center of the inside of porous wall is used as a reference, 50% by mass of specific noble metal is carried.
