Abstract: The invention relates to a catalyst which contains copper and which is provided for decomposing N2O. The inventive catalyst contains a compound of general formula MxA12O4, in which M represents Cu or mixtures of Cu with Zn and/or Mg, wherein x has a value ranging from 0.8 to 1.5. The invention also relates to a method in which the inventive catalyst is used in order to catalytically decompose N2O which is pure or which is contained in a gas mixture at an increased temperature.
