A simple quantum chemical theory of dissociative adsorption is introduced and applied to the chcmisorption of hydrogen on copper. Hydrogen is predicted to chcmisorb more readily on the stepped (311) surface than on either of its component low index fa;ILcs.
The electrooxidation of CO adsorbate on well ordered Pt(ll1) surfaces is studied through a flow-cell technique. Potentiodynamic sweeps and potential steps are used to characterize the kinetic behaviour of the adsorbate. The effect of surface disturbance when the electrode is cycled into the oxide fo
