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)xSiR4-x (I)(Hal)xSi(OR1)4-x (II)(Hal)xSi(NR1R2)4-x (III)RxSi(OR1)4-x (IV)RxSi(NR1R2)4-x (V)(R1O)xSi(NR1R2)4-x (VI)
