Oxygen adsorption on Pt(110)(1 × 2) at 100 K

Oxygen adsorption on Pt(110) has been studied at 100 K by work function measurements, photoemission of adsorbed xenon, electron induced desorption and thermal desorption spectroscopy.

Description
Summary:Oxygen adsorption on Pt(110) has been studied at 100 K by work function measurements, photoemission of adsorbed xenon, electron induced desorption and thermal desorption spectroscopy. The adsorption process takes place in two steps. In the first one oxygen is adsorbed in the valleys of the reconstructed surface along the (110) direction. The molecularly adsorbed species is bound to the surface with a binding energy of 12 kcal/mol. In the second step oxygen molecules are adsorbed on the (111) microfacets with a binding energy of 10 kcal/mol.
