A zeolite-coatable metallic foil, in particular in the form of a honeycomb body, is formed of a steel containing chromium and/or aluminum and having a surface. An oxide layer covers the surface. A ceramic washcoat on the oxide layer acts as a bonding layer for receiving a zeolite layer. A process for producing a metallic foil coated with zeolite, in particular in the form of a honeycomb body, includes oxidizing a steel foil containing chromium and/or aluminum to form a finely grained aluminum oxide layer on a surface. A ceramic washcoat acting as a bonding layer is applied to the oxide layer. A zeolite layer is applied to the ceramic bonding layer.
