Abstract

The present invention relates to a nitrous oxide decomposition catalyst, the preparation and use. The catalyst contains rhodium on a catalyst carrier. The carrier is obtained by mixing zirconium dioxide powder with a silicon compound as binder, to form a kneadable composition, homogenizing the composition, shaping the composition into shaped articles, drying and calcination, wherein the binder is selected from silicon compounds of general formulae (I) to (VI)(Hal)SiR  (I)(Hal)Si(OR)  (II)(Hal)Si(NRR)  (III)RSi(OR)4-  (IV)RSi(NRR)  (V)(RO)Si(NRR)  (VI)
