Abstract:

The energetics of pyridine adsorption onto a Au311 single crystal electrode surface have been investigated using chronocoulometry. Adsorption parameters such as the relative Gibbs surface excess, the Gibbs energies of adsorption, and electrosorption valencies have been determined. The data have been analyzed in terms of both the electrode potential and surface charge density. Over the potential region investigated pyridine has been found to adsorb in the vertical orientation with the nitrogen end of the pyridine molecule facing the AuA311 surface. The Gibbs energies of adsorption were calculated using the Henrys Law isotherm.
