Abstract: The present invention relates to a selective catalytic reduction catalyst comprising a porous wall-flow filter substrate; wherein in the pores of the porous internal walls and on the surface of the porous internal walls, the catalyst comprises a selective catalytic reduction coating comprising a selective catalytic reduction component comprising a zeolitic material comprising one or more of copper and iron. The present invention further relates to a process for preparing a selective catalytic reduction catalyst using particles of a carbon-containing additive and an aqueous mixture comprising said particles of a carbon-containing additive.
