Abstract

The adsorption of ammonia, oxygen, and the NH3 + O2 mixture on solid solutions CdxHg1 − xTe is studied. The low adsorbability of the mixture, as compared to that of the individual components, is established. Conclusions are drawn as to the nature of its active centers. Schemes for the combined adsorption of ammonia and oxygen are proposed. The temperature areas of tentatively highest catalytic activity of CdTe and CdHgTe in the reaction of ammonia oxidation are established. The formation of gaseous nitrogen in the final products is demonstrated. The degree of ammonia’s transformation into nitrogen is 97–99%. It increased with a rise in temperature and did not depend on the initial ammonia concentration.
