Abstract

The invention relates to: a catalytic composition that is active in the selective catalytic reduction of nitric oxides, containing an iron-containing MFI-type zeolite and an iron-containing BEA-type zeolite, wherein the weight average particle size d50 of the MFI-type zeolite and the BEA-type zeolite is different; a method for producing an SCR catalyst; and the SCR catalyst produced in this way. The adhesion of the coating is improved in that the weight average particle sizes of the MFI-type and BEA-type zeolites are different.
