Abstract
A method for decomposing N2O is described. The method uses, as a catalyst, an oxide based on cerium and lanthanum, which further includes at least one oxide of an element chosen from zirconium and rare earths other than cerium and lanthanum. This catalyst is stable, enabling it to be used at high temperatures.
