The present disclosure relates to an aqueous suspension comprising water, a source of one or more of a vanadium oxide and a tungsten oxide, and particles of an oxidic support; wherein the particles of the aqueous suspension exhibit a polymodal particle size distribution characterized by a particle size distribution curve comprising a first peak with a maximum M(I) in the range of from 0.5 micrometers to 15 micrometers and a second peak with a maximum M(II) in the range of from 1 micrometers to 40 micrometers, wherein M(I):M(II) is less than 1:1.

Selective catalytic reduction suspension

The present invention relates to a catalyst for the selective catalytic reduction of nitrogen oxide, the catalyst comprising a first coating comprising a 12-membered ring pore zeolitic material comprising a first metal which is one or more of copper and iron, and a second coating comprising an 8-membered ring pore zeolitic material comprising a second metal which is one or more of copper and iron.

High ammonia storage capacity SCR catalysts

The present invention relates to a catalyst for the oxidation of hydrocarbon and the selective catalytic reduction of nitrogen oxides, the catalyst comprising a 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 substrate extending therethrough; and a coating disposed on the surface of the internal walls of the substrate, wherein the surface de-fines the interface between the passages and the internal walls, wherein the coating comprises a platinum group metal component supported on a first oxidic material and further comprises a mixed oxide of vanadium and one or more of iron, erbium, bismuth, cerium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, scandium, terbium, thulium, ytterbium, yttrium, molybdenum, tungsten, manganese, cobalt, nickel, copper, aluminum and antimony, wherein the mixed oxide is supported on a second oxidic material.
