The potential of zero charge of 0.3 V vs. NHE agrees very well with earlier values obtained by different methods. The observation of the potential of zero charge of this interface requires a specific pH (pH 4) and anomalously low electrolyte concentrations (&lt;10<sup>-3<\/sup> m). By comparison to gold and mercury double-layer data, we conclude that the diffuse double layer structure at the Pt(111)-electrolyte interface deviates significantly from the Gouy-Chapman theory in the sense that the electrostatic screening is much better than predicted by purely electrostatic mean-field Poisson-Boltzmann theory.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/anie.201911929 Authors: Kasinath Ojha, Nakkiran Arulmozhi, Diana Aranzales, Marc T.
