The surface coverage of a series of rhenium-alumina catalysts prepared by equilibrium adsorption was determined by ion scattering spectroscopy (ISS) and infrared spectroscopy (IR). The coverage results were compared with those determined from previously published CO, chemisorption data. The ISS res

✦ Synopsis
The electronic structure of the 001 and 110 ␣-alumina surfaces was Ž . determined by periodic Hartree᎐Fock method in statically relaxed geometries. Both 001 Ž . and 110 surfaces generate specific surface states into the energy gap. Significant influence of charge-transfer effect on the surface᎐adsorbate potential is possible in both cases studied. The inclusion of the exponential part to the standard potential forms was suggested for the description of the interaction potential in such cases.
