Fig. 1: Proton electrosorption potentials \({U}_{{\rm{RHE}}}^{{\rm{sorp}}}\) for Pt(111) and Pt(100).

From: Electrosorption at metal surfaces from first principles

Fig. 1

Left panels: Calculated shifts within the CHE (solid line), the second-order (dashed line) and the FGC (dotted line) approach. Shown are results for 1/4 ML (red) and 1 ML (blue) hydrogen coverage on the surface. Right panels: Experimental shifts derived from works by Rizo et al. (orange squares)48 and Kamyabi et al. (black stars)49 for Pt(111), as well as Zheng et al. (orange circles)50 for Pt(100). The linear fits are guide to the eye.
