Abstract:
IR spectroscopy has been used in determining the sources of the deactivating effect of CO and O2 in the reaction of NO reduction by carbon monoxide in the presence of oxygen on Pd/γ-Al2O3. The observed nitrosyl and carbonyl complexes are stabilized on Pd in different degrees of oxidation. The lower NO conversions in mixtures with excess CO are explained by competitive adsorption of NO and CO. With increasing concentration of O2 up to 0. 3% by volume (m equals 1. 15), the degree of oxidation of the Pd increases. This work is pertinent to the treatment of exhaust gas.
