FTIR spectroscopy and thermodynamics of CO and H2 adsorbed on γ-, δ- and α-Al2O3
The adsorption of CO and H 2 at the surface of transitional (γ and δ) and corundum (α) phases of Al 2 O 3 is studied by means of FTIR spectroscopy at temperature variable in the 293-60 K (CO) and 293-20 K (H 2 ) intervals with the aims of better clarifying the nature of the surface Lewis centres and...
