Abstract (en)

[origin: DE19841740A1] The aim of the invention is to produce a catalyst for selectively decomposing N2O in a mixture of nitrous gases which should be able to be used at temperatures ranging from 700 DEG C to at least 1000 DEG C without impairing the catalytic activity thereof. To this end, the catalyst is comprised of a porous ceramic supporting material and of a catalytically active phase, whereby the supporting material is comprised of up to at least 95 mass per cent of one or several alkaline-earth compound(s). The inventive catalyst can preferably be used during the production of nitric acid.
