Study of the (210) face of gold in aqueous solutions

Abstract

Among all the gold faces studied to date, the (210) face has the most negative pzc and therefore should be less affected by preoxidation than the other faces. But the (210) gold face-sodium fluoride solution interface is ideally polarizable only in a short range of potential. Nevertheless, differential capacity-potential curves have been tentatively exploited. There seems to be adsorption of the fluoride ions on the (210) face of gold. The inner-layer capacity-charge curves are discussed.
