Abstract
The joint adsorption of CO and NO molecules on the surface of nanodimensional nickel clusters formed on the Mo(110) face of a thin MgO(111) magnesium oxide film under conditions of ultrahigh vacuum is investigated by methods of infrared reflection and thermal desorption spectroscopy. It is revealed that the adsorption of the NO molecules changes significantly the state of the adsorbed CO molecules. Based on an analysis of thermal desorption and IR spectra, a conclusion can be drawn that the adsorption of the NO molecules stimulates the migration of the CO molecules from the metal cluster surface to the boundary between the cluster and oxide accompanied by a decrease in the tilt angle of the molecular axis to the surface.
