Abstract

A catalyst comprising a metallic carrier having a catalytically active metal-containing surface layer, the catalytic metal being other than a noble metal, wherein the catalytically active metal-containing surface layer is formed directly on the carrier by an etching treatment with an oxidizing inorganic acid which at least partially removes one or more metals from the surface of the metallic carrier, followed by chemical reduction with hydrogen.
