ABSTRACT:
A catalyst, which is capable of controlling not only HC, CO and NO.sub.x, but also H.sub.2 S emission from the tail pipe of catalytic converter automobiles, is made of platinum-group metals promoted by rare earth oxides and containing a metal ferrite. The ferrite is present in an H.sub.2 S gettering amount and in an amount up to about 20 weight % of the catalyst. The catalyst comprises an alumina support and is applied as a washcoat to a substrate, such as a honeycomb monolith made from ceramic or metal.
