  • Hydrogen sulfide-suppressing catalyst system
    Patent number: 5196390
    Abstract: H.sub.2 S formation by three-way catalyst is suppressed by incorporating nickel, manganese or iron oxides into an undercoat layer disposed on a substrate, such as a monolith substrate. A topcoat overlying the undercoat is comprised of a three-way catalyst material which includes one or more of platinum, rhodium and palladium as catalytic metals.
