To produce the catalyst (2), a) functional particles (8) are provided, having a catalytically inactive pore former (4) as support surrounded by a layer(5) of a catalytically active material, b) the functional particles (8) are processed with further inorganic particles (10) to give a catalytic material(12), c) the catalytic material(12) is treated thermally to form the ceramic catalyst (2), wherein the catalyst (2) comprises at least porous catalytically inactive cells (20) –which are formed by the pore formers (4) in the functional particles (8), –which are embedded in a matrix (24) comprising the further inorganic particles (10), –which form a porous structure (18) and –which are at least partly surrounded by an active interface layer (22) comprising the catalytically active material of the layer (5) of the functional particles (8). An SCR catalyst (2) produced in this way has an improved NO conversion rate compared to a conventionally produced SCR catalyst. |
