    Abstract: Exhaust gases of internal combustion engines are contacted with a ruthenium-iridium catalyst to provide less objectional products suitable for discharge to the atmosphere. The ruthenium-iridium catalyst has been found to be extremely effective in promoting the removal of nitrogen oxides, carbon monoxide and unburned hydrocarbons from automobile exhaust gases. The catalyst is more effective than catalysts containing either the ruthenium component or the iridium component alone.
