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

An aqueous suspension comprising water, a zeolitic material and one or more of copper and iron, and a chelate complex comprising a zirconium ion and a bidentate organic ligand bonded to said zirconium ion via zirconium oxygen bonds from two oxygen atoms comprised in said ligand, said chelate complex being dissolved in the water.

Aqueous suspension comprising a zeolitic material and a zirconium chelate complex

Disclosed is a catalyst, preferably for use in selective catalytic reduction (SCR), said catalyst comprising one or more zeolites of the MFI structure type, and one or more zeolites of the BEA structure type, wherein at least part of the one or more zeolites of the MFI structure type and at least part of the one or more zeolites of the BEA structure type respectively contain iron (Fe). Furthermore, an exhaust gas treatment system is described, comprising said catalyst as well as a process for the treatment of a gas stream comprising NOusing said catalyst as well.
