A catalyst comprising a metallic carrier having a catalytically active metal-containing surface layer, the catalytic metal being other than a noble metal, whereby the catalytically active surface layer is formed out of a homogeneous metallic carrier by oxidizing in an oxidizing gas such as air and subsequently reducing with hydrogen the surface of the metallic carrier at a temperature at which the active metal is substantially not sintered, characterized in that the carrier is a web or felt of fibers with a diameter between 4 and 100 microns.
