Abstract

Carbon monoxide, hydrocarcarbons and nitrogen oxides contained in hot exhaust gas from an internal combustion engine are converted by passing them in contact with a catalytic composite comprising a platinum-rhodium or palladium-rhodium catalyst promoted by uranium in intimate admixture therewith and 2 dispersed on a high-surface-area refractory inorganic oxide.
