Abstract: The invention concerns an aluminium oxide catalyst containing silver, the catalyst containing in addition copper oxide and, optionally, other promoters and active components. This catalyst is used to decompose pure nitrous oxide (N2O) or nitrous oxide in gas mixtures at elevated temperatures, and exhibits high activity.
