“…2 and 4 of ref. 20 and amount to about 48 mF cm À2 and +11 mC cm À2 , respectively. Finally, the surface dipole potential, c w , of the water molecules on bare gold at the high charge density of +11 mC cm À2 was assumed, as a rough approximation, to be equal in magnitude and opposite in sign to the limiting positive c w value on bare mercury, which is approximately equal to +60 mV.…”

A procedure for estimating the surface dipole potential of monolayers adsorbed on electrodes

The extrathermodynamic potential difference Df across an electrified interface enclosed between a bulk metal M and a bulk aqueous phase does not depend on the content of the interface, at constant applied potential E. By equating at constant E the expression of Df for an electrode coated by a self-assembled monolayer (SAM) to that for the corresponding bare electrode immersed in the aqueous solution of a nonspecifically adsorbed electrolyte, it is possible to estimate the surface dipole potential c SAM of the SAM. If the molecules of the SAM form a bond M-X with the metal M, this procedure requires an independent knowledge of the surface dipole potential c M-X SAM due to such a bond. The other way round, if the c SAM value is known by independent means, the procedure allows an estimate of c M-X SAM . The selfconsistency of this procedure was tested with SAMs of ten different thiolated peptides covalently bound to a mercury electrode, where c SAM can be determined independently by expanding a mercury drop. The procedure was then applied to the estimate of the c SAM value of a peptide SAM on a polycrystalline gold electrode.

“…Before each experiment the electrode was cleaned in deoxygenated supporting electrolyte NaF by a few cycles involving anodic oxidation of the surface and its subsequent reduction. This procedure was performed until the current-potential curves exhibited the known features already reported (5). Next the desired electrolyte was added to the supporting electrolyte solution at potentials corresponding to the so-called double layer region and the capacitypotential measurements were carried out.…”

EDWARD DUTKIEWICZ and PIOTR SKOLUDA. Can. J. Chem. 67, 141 1 (1989).Studies on the specific adsorption of succinate and maleate anions at polycrystalline gold electrode from solutions at constant cationic strength are reported. The adsorption has been studied by differential capacity -potential measurements. The adsorption can be described by one-constant virial isotherm. The basic parameters of this isotherm are determined. Our experimental results are partly interpreted with the help of the results of the adsorption of dicarboxylic anions on the (210) and (3 11) IntroductionThe adsorption of dicarboxylic anions on single crystals of gold so far has been the object of two quantitative studies (1,2). In ref. 1 the adsorption of succinate (Su) and maleate (Ma) anions was investigated on a (210) face of gold using the approximate method for determining the charge adsorbed specifically from solutions of mixed electrolytes of different symmetry at constant cationic strength (3). The adsorption was found to increase from Su to Ma anions and was interpreted in terms of the geometric structure and the electric properties of both anions. In ref. 2, thermodynamic analysis of the adsorption of dicarboxylic anions on a (3 1 1) face of gold, carried out using the same method of calculation, shows that the Su anions are more strongly adsorbed than Ma anions. These results were interpreted not only in terms of the geometric structure and electric properties of a given ion but also of the arrangement of metal atoms on the electrode surface. In this work, we decided to study the adsorption of succinate and maleate anions on the polycrystalline gold electrode.
