Abstract
Mo(100)-c(2 x 2)-N, as a model surface for the real Mo2N catalyst, was prep ared. The adsorption of CO and (NO)-N-15 on this model surface were studied by high-resolution electron energy loss spectroscopy (HREELS). It was foun d that CO and O-15 not only could be adsorbed on the top of the Mo sites bu t 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 su rface are ail active for CO and (NO)-N-15 adsorption. (C) 2000 Elsevier Sci ence B.V. All rights reserved.
