ABSTRACT:
The invention relates to a method for the catalytic decomposition of N2O in a gas containing N2O in the presence of a catalyst, wherein the catalyst comprises a zeolite that has been loaded with a first metal selected from the group of noble metals consisting of ruthenium, rhodium, silver, rhenium, osmium, iridium, platinum and gold, and with a second metal selected from the group of transition metals consisting of chromium, manganese, iron, cobalt, nickel and copper, and wherein the loading of the zeolite with metals has been obtained by first loading the zeolite with the noble metal and then with the transition metal, as well as a catalyst for this method and a method for the preparation of this catalyst.
