ResumoThe catalytic activity of several MgONiO catalysts has been tested for the decomposition of N2O. The atomic nickel content ranges from 0.15% to 50%. It has been clearly shown that the activity per nickel ion is enhanced by the dilution. The occurrence of a minimum in the apparent activation energy in the region 1 to 10 at. % nickel is observed. The results are discussed in terms of the different ionic and electronic interactions which develop according to the nickel content. The determination of the catalytic activity on a lithium-containing catalyst confirms the results already established that the presence of lithium increases the apparent activation energy.
