Cu–Al–Ox mixed metal oxides with intended molar ratios of Cu/Al = 85/15, 78/22, 75/25, 60/30, were prepared by thermal decomposition of precursors at 600 °C and tested for the decomposition of nitrous oxide (deN2O).

It was recently discovered that iodine exerts a pronounced catalytic influence on the thermal decomposition of nitrous oxide. Bromine and chlorine have now been found to have similar effects. The reactions are of the first order with respect to the nitrous oxide and there appears to be little doubt that decomposition into a nitrogen molecule and an oxygen atom occurs under the influence of the halogen. The balance of evidence is in favour of the hypothesis that the effective catalyst is the free halogen atom. Whether the oxygen atom from the nitrous oxide remains attached to the halogen for a finite time cannot be definitely stated.
