Three different CuO-containing samples have been studied as catalysts for N2O decomposition. Among the studied samples, hydrotalcite-derived mixed oxides (CuO-MgO-Al2O3) have been found to be the most active catalyst. g-Alumina-supported copper oxide (CuO/Al2O3) was only slightly less active, while the catalytic activity of pure CuO was significantly lower than the rest of the samples. Only a very small amount of chemisorbed N2O has been found on the surface of the catalysts under the reaction conditions. N2 molecules produced from chemisorbed nitrous oxide desorbed directly to the gas phase, while part of oxygen was bonded to the catalyst surface.
