Adsorption of Pyridine at the Au(311) - Solution Interface

Abstract

The energetics of pyridine adsorption onto a Au(311) 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 Au(A311) surface. The Gibbs energies of adsorption were calculated using the Henry's Law isotherm.
