Correction to “Non-monotonic Surface Charging Behavior of Platinum: A Paradigm Change” Jun Huang, Ali Malek, Jianbo Zhang,* and Michael H. Eikerling* J. Phys. Chem. C 2016, 120 (25), 13587−13595. DOI: 10.1021/acs.jpcc.6b03930 We feel compelled to report an inadvertent mistake in our article referred to above with respect to the potential scale used in presenting and discussing the surface charging relation of Pt. In the theoretical derivation of this charging relation, which constitutes the main body of the article, the metal (or electrode) potential ϕbM is referenced to the potential in the solution phase at a far distance from the electrode. In doing so, we have implemented a constant, pH independent potential scale. However, experimental data reporting the results of electrode polarization studies commonly employ the RHE as a reference for the potential of the working electrode. This practice becomes misleading and constitutes a latent source of error, when the pH is an independent variable of the system under study, as is the case for our work. Referencing the potential scale in Figures 5 and 6 and the TOC graphic to the RHE scale was thus wrong. Specifically, in the label at the abscissa of those figures, RHE should be replaced by SHE. Here is a complete list of corrections: (1) In the label at the abscissa of the left figure in the TOC graphic, RHE should be replaced by SHE. (2) The corrected sentence after eq 6 reads “where (ϕMb − ϕSb) is exactly the electrode potential defined with respect to the SHE.” (3) In the labels at the abscissas of the Figure 5, RHE should be replaced by SHE. In addition, the figure caption to panel a should be corrected as “Fitting of the total charge density as a function of electrode potential vs SHE of a Pt(111) electrode in 0.1 M HClO4 electrolyte solution”. (4) In the label at the abscissas of the Figure 6, RHE should be replaced by SHE.
