ABSTRACT:
Process and catalyst for the catalytic conversion of nitrogen oxides (NO.sub.x), unburned hydrocarbons and carbon monoxide in internal combustion engine exhaust gases. The catalyst comprises rhodium as the essential active component, preferably composited with a nickel component. These catalysts are found to be exceptionally resistant to poisoning by sulfur and lead compounds present in the exhaust gases.
