Catalytic decomposition of nitrous oxide in the presence of oxygen is achieved using a solid oxide solution of the formula:La0.8Sr0.2MO3+/- DIFFERENTIAL where: M is a transition metal, and is preferably selected from the group consisting of Cr, Mn, Fe, Co and Y; and DIFFERENTIAL is the deviation from stoichiometric balance; or:La1.8Sr0.2CuO4+/- DIFFERENTIAL where: DIFFERENTIAL is the deviation from stoichiometric balance. The solid oxide solution catalyst exhibits catalytic activity for nitrous oxide decomposition which rivals or exceeds that of dispersed noble metals on alumina.
