The use of a homogeneous catalyst of spinel structure and formula ZnAl2O4 or an oxide of spinel structure (normal or inverse) other than ZnAl2O4, for the treatment of exhaust gases with a high O2 content, is claimed. Pref. the oxide of spinel structure (normal or inverse) corresp. to the formula:- AB2O4 A = at least one element from gps. IIa, IIb, IIIb, IVb and Vb or any transition element. B = at least one element from gps. IVa, VIa, VIIa, VIIIa, Ib to Vb. Esp., A = Mg, Ti, Mn, Fe, Co, Ni, Cu, Zn, or Sn, and B = Ti, Mn, Cr, Fe, Co, Ni, Cu, Zn, Al, Ga, In, Sn or Sb. More pref, B = Al or Ga.
