Abstract:
The adsorption of reactant mixtures is quantitatively and qualitatively different from the adsorption
of the individual reactants. Thus, O2 is almost not adsorbed on ZrO2; however, a considerable concentration
of molecular oxygen was detected among the products of desorption after the adsorption of a mixture of NO +
O2 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 O2. Among the qualitative differences is the formation of the radical
anion on the surface only upon the adsorption of the mixture of NO + O2. Similarly, the number of desorbed
molecules upon the simultaneous adsorption of C3H6, NO, and O2 was much greater than that upon their
individual adsorption; this is related to the formation of paramagnetic and nonparamagnetic NO2–hydrocarbon
complexes on the surface, which contained the NO2 group and a hydrocarbon fragment.
