Preparation and adsorption properties of Mo N model catalyst

Mo 100.`c 2=2.-N, as a model surface for the real Mo2N catalyst, was prepared. The adsorption of CO and 15NO on this model surface were studied by high-resolution electron energy loss spectroscopy HREELS.. It was found that CO and 15NO not only could be adsorbed on the top of the Mo sites but also could react with surface N sites to form surface NCO and N2O species, respectively. This indicated that both the Mo atoms and N atoms of the surface are all active for CO and 15NO adsorption. q2000 Elsevier Science B.V. All rights reserved
