โœฆ Synopsis

The formation of methanol adsorbate as a structure sensitive process was studied on platinum single crystal surfaces. The measurements were performed on reproducibly prepared, clean and either well ordered ("undisturbed") or cycled ("disturbed") Pt(100) and Pt(ll1) single crystal electrodes. Essential differences were found. The data are interpreted in terms of parallel pathways leading to both COH and CO as adsorbed intermediates in a ratio depending on the surface structure present on the single crystal electrode.

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

The reaction of C2H 4 on Pt{111} at 300 K has been investigated by single crystal adsorption calorimetry. The initial heats of adsorption and the initial sticking probability are 174 kJ/mol and 0.67 respectively. The adsorption heat versus coverage data shows a remarkable minimum which serves as a b
