CO adsorption on gold clusters stabilized on ceria-titania mixed oxides: Comparison with reference catalyst
Article Abstract:
A description of the Fourier transform infrared (FTIR) spectra of CO adsorption from 120K upto room temperature on two gold catalysts supported on various mixed ceria-titania oxides is compared with those available on Au/TiO2 and Au/Fe2O3 reference catalyst given by the World Gold Council. CO adsorption on the four varying gold catalysts revealed that the nature of the exposed sites and the strength of the adsorption are different.

Surface and subsurface hydrogen: Adsorption properties on transition metals and near-surface alloys
Article Abstract:
Thermochemical properties of surface and subsurface atomic hydrogen on a variety of pure metals and near-surface alloys (NSAs) were studied using periodic, self-consistent DFT-GGA calculations. On NSAs, hydrogen is observed to bind more weakly than it binds to the corresponding pure metals, although the binding is stronger than it is with most noble metals.
