Abstract:
An emission control catalyst composition comprising a supported bimetallic catalyst consisting of gold and a metal selected from the group consisting of platinum, rhodium, ruthenium, copper and nickel is disclosed. Also disclosed is a catalytic convertor comprising a substrate monolith coated with the emission control catalyst composition and a lean burn internal combustion engine exhaust gas emission treatment system comprising the catalytic convertor. A variety of processes for preparing the catalyst composition are claimed.
