Electrochemical Indication of Surface Reconstruction of (100), (311) and (111) Gold Faces in Alkaline-Solutions

The specific adsorption of OH- anion and the changes in the surface atomic structures of (100), (311) and (111) gold faces with charge density are discussed on the basis of cyclic voltammograms and differential capacity-potential curves obtained in dilute NaOH solutions.
