Abstract

The present invention relates to a selective catalytic reduction catalyst for the treatment of an exhaust gas of a diesel engine comprising: a flow-through substrate comprising an inlet end, an outlet end, a substrate axial length extending from the inlet end to the outlet end and a plurality of passages defined by internal walls of the flow through substrate extending therethrough; a coating disposed on the surface of the internal walls of the substrate, wherein the coating comprises a non-zeolitic oxidic material comprising manganese and one or more of the metals of the groups 4 to 11 and 13 of the periodic table, and further comprises one or more of a vanadium oxide and a zeolitic material comprising one or more of copper and iron.
