Abstract: The invention relates to a catalyst for decomposing nitrous oxide, to a method for producing same, and to the use thereof. The catalyst contains rhodium on a catalyst support, and the catalyst support is produced by mixing zirconium dioxide powder with a silicon compound as a binder and water so as to form a kneadable mass, homogenizing the mass, molding the mass into molded bodies, drying, and calcining. The binder is selected from silicon compounds of the general formula (I) to (IV) (Hal)xSiR4-x(l) (Hal)xSi(OR')4-x(II) (Hal)xSi(NR R )a-x(III) RxSi(OR')4-x (IV) RxSi(NR R )4-x(V) (R O)xSi(NR R )4-x(VI), where Hal independently of one another represents halogen (F, Cl, Br, or I), R independently of one another represents H or an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, arylalkyl, or aryl group, R , R independently of one another represent H or an optionally substituted alkyl, acyl, arylalkyl, or aryl group, and x represents 0 to 4.
