The present invention provides an exhaust gas catalyst, wherein it consists of about 50 to about 95% by weight of silicon carbide and about 5 to about 50% by weight of an alloy of silicon with one or more metals of the group copper, iron, cobalt, nickel, chromium, vanadium, molybdenum, manganese, zi
The present invention provides an exhaust gas catalyst, wherein it consists of about 50 to about 95% by weight of silicon carbide and about 5 to about 50% by weight of an alloy of silicon with one or more metals of the group copper, iron, cobalt, nickel, chromium, vanadium, molybdenum, manganese, zinc, silver, platinum, palladium or other catalytically-active metals, the catalytically-active surface of which has optionally been activated by oxidation and/or chemical after-treatment. The present invention also provides processes for the production of this catalyst.
