Abstract :
Coadsorption of NO and CO molecules on the Ni clusters deposited on MgO(111) film formed on a Mo(110) crystal has been studied by reflection–absorption infrared spectroscopy (RAIRS) and temperature programmed desorption (TPD). It is found that adsorption of NO molecules strongly affects the state of CO molecules, which were initially adsorbed on the Ni clusters. The observed features in RAIRS and TPD spectra are attributed to the change of the CO adsorption site and geometry, which is induced by NO adsorption.
