ABSTRACT:
Metal alloy having high catalytic activity. It comprises a refractory base metal mass containing carbon and at least one metal of the platinum type, the surface of which has been subjected to intergranular acid corrosion which produces microfissures and causes the formation of microcrystals of the platinum metals.
Application in exhaust catalytic converters.
The present invention relates to refractory metallic alloys exhibiting a high catalytic activity which are particularly useful for reducing exhaust gas pollution from automobiles.
