    Notes:
    The adsorption of CO on Cu (211), serving as model system for the adsorption of CO in stepped surfaces, has been investigated using electron energy loss spectroscopy (EELS). At a surface temperature of 110 K, CO adsorbs nondissociatively and is drawn exclusively to descending step sites in this system. On-top and bridge sites are sequentially populated with the CO axis being perpendicular to the surface. In addition, at low coverage, a molecular state is observed, for which the CO axis is strongly inclined. © 1999 American Institute of Physics.

    Notes:
    Abstract Supported chromium oxide catalysts containing 0.5 and 4.0 wt% Cr, respectively, on a 7 wt% La2O3/ZrO2 carrier were studied by in situ EPR equipped with on-line GC during the catalyst pretreatment in flowing H2 and the aromatization of n-octane in the range 293〈T〈823 K. Active catalysts contain almost exclusively Cr3+ in the form of Cr2O3 clusters and isolated, coordinatively unsaturated Cr3+ species on the surface. The latter appear to be less sensitive to poisoning by coke deposition and govern residual catalytic activity.
