The adsorption of CO and H2 at the surface of transitional (γ and δ) and corundum (α) phases of Al2O3 is studied by means of FTIR spectroscopy at temperature variable in the 293-60 K (CO) and 293-20 K (H2) intervals with the aims of better clarifying the nature of the surface Lewis centres and evaluate the thermodynamics of the adsorption process.
