- Abstract
The adsorption of reactant mixtures is quantitatively and qualitatively different from the adsorption of the individual reactants. Thus, O is almost not adsorbed on ZrO; however, a considerable concentration of molecular oxygen was detected among the products of desorption after the adsorption of a mixture of NO + O and the total amount of desorbed molecules was greater by a factor of 10 than their total amount after the individual adsorption of NO and O. Among the qualitative differences is the formation of the O radical anion on the surface only upon the adsorption of the mixture of NO + O. Similarly, the number of desorbed molecules upon the simultaneous adsorption of CH, NO, and O was much greater than that upon their individual adsorption; this is related to the formation of paramagnetic and nonparamagnetic NO-hydrocarbon complexes on the surface, which contained the NO group and a hydrocarbon fragment.
