Abstract
A catalyst is made of at least two metal foil strips, the transverse corrugations having been formed in at least one of them. The metal foil strips are formed into a honeycomb containing channels. The strips are coated with a support or with supports, and at least one catalytically active agent such as a noble metal is added to the coated strips in order to produce a catalytic surface. In this case the catalytic surface has the physical structure derived from the coating. The honeycomb has at least two catalytic surfaces differing from each other with respect to at least the support or the physical structure.
