Abstract: | Weight-space and IR spectroscopic methods have been used to investigate the reaction of NO and N2O with the surface of a copper-chromium oxide catalyst in the form of copper chromite with a 20% excess of Cr2O3. Comparisons have been made between the relative reactivities of the different oxides (NO, N2O, O2) in oxidation of the Cu+ and Cuo surface centers. The role of these centers in oxidation of CO by oxygen and by nitrogen oxides is discussed.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 21, No. 3, pp. 338–343, May–June, 1985. |
