Abstract
The invention relates to a process for the production of catalysts for the reduction of nitrogen oxides from exhaust gases and similar chemical air cleaning processes, in which a catalytically active material is deposited and bonded on a carrier made of metal, preferably stainless steel. The carrier is preferably in the form of a perforated metal plate, or of rib mesh, or a grid, preferably fabric, honeycombed or knitted material made of metal wire, or a similar material with a high specific surface. To simplify manufacturing and to improve the characteristics of the catalysts, the invention proposes the use of an acid which etches the surface of the metal carrier as the binder for the catalytically active material.
