Abstract
The vibrational perturbations induced in the IR spectra of methane and of dihydrogen by the non-dissociative adsorption on the (01\(\overline 1\)2) and (11\(\overline 2 \)0) faces of α-chromia are illustrated and compared. It is concluded that both molecules are adsorbed on Cr3+ sites and that the involved forces are mainly of the electrostatic type. The resulting situation is compared with that found on the more basic MgO. The problems associated with the C–H and H–H bond activations on transition metal oxides are also discussed.
