Abstract:
Oxygen-rich exhaust gases, for example those emanating from internal combustion engines, e.g., diesel engines, are catalytically treated/converted to reduce emissions of NO.sub.x, in the presence of a catalytically effective amount of either (a) a spinel mass oxide essentially having the formula ZnAl.sub.2 O.sub.4, or (b) a normal or inverse spinel oxide other than ZnAl.sub.2 O.sub.4, for example ZnGa.sub.2 O.sub.4, SnZnGa.sub.2 O.sub.4 or MgAl.sub.2 O.sub.4.
