In the double layer potential region, we could connect the charge density of the adsorbate-free Pt(111) surface with the electrode potential. Going to higher potentials, however, demands the consideration of appropriate adsorbate compositions (i.e., oxygen atoms O * , hydroxide molecules OH * and water molecules H 2 O * ) along with surface oxidation effects. In the following, a structure-potential-relation connecting a given electrode potential with the corresponding equilibrium surface structure as predicted from literature is formulated and applied. In this spirit, the theoretical studies by Kronberg et al. and Sakong et al. have recently included hydrogenated Pt(111) surfaces for approximation of the low potential region. So far, the authors are not aware of similar approaches for modeling the higher potential region consistently including all the relevant oxygenated adsorbates.
