| The catalytic reaction between CO and NO was studied on two different model catalysts using polarization-modulation infrared reflection absorption spectroscopy (PM-IRAS) technique within a wide pressure regime (10-6- 240 mbar). On the atomically flat Pd(111) surface, besides the behavior of the adsorbed reactant species, formation of an isocyanate (-NCO) species was followed under high pressure conditions. The relationship between the –NCO formation and the total pressure of the reactants as well as the CO/NO partial pressure ratio was examined. The reaction kinetics was also investigated by gas phase infrared spectroscopy. The Pd (111) single crystal studies have been extended to a more complex and realistic model catalyst prepared by depositing Pd clusters onto a crystalline SiO2 thin film grown on an atomically clean Mo(112) substrate.
