PROBLEM TO BE SOLVED : To provide a mixed oxides catalyst which is suitable for the selective oxidation to CO2 and the full oxidation to CO2 and H2O of VOC, in the same manner, for the decomposition of ester of nitrous acid (nitrogen protoxide) to nitrogen and oxygen, and for the combustion of CO, H2 and CH4 of the gas exhausted from anode of fuel cells; which gives a high heat stability and high activity even after aging in high temperature; and which does not request one or more process of impregnation after the impregnation in lanthanum nitrate solution in an industrial manufacture. SOLUTION : The problem is solved by the mixed oxides catalyst which includes oxides of manganese and copper, and oxides of rare-earth metals selected from lanthanum oxides and neodymium oxides, having a percentage composition by weight expressed as MnO, CuO, La2O3 and/or Nd2O3 respectively of 35-56 wt.%, 19-31 wt.% and 20-37 wt.%.
