Trasatti and Lust reported in that the PZC of Au(111) in alkaline solution is 0.56± with Vaspsol, with the CP-HS-DM (which also uses the VASPsol implicit solvation model but updates charges and capacitance differently), and obtained with Born-Oppenheimer DFTMD with the CP2K/Quickstep package. The estimated PZC is 0.5 V vs SHE for all these computational methods, however, the simulated interfaces do not have ions in the solution. Some other theoretical estimations of the PZC obtain values that are a bit higher, as for example 0.56, in Ref. Our result for the pure water interface is 0.63 ± 0.15 V, so it is consistent with the aforementioned ones within the estimated regression error. The results for the other simulations show a shift induced by the ionic presence, so the PZC of the LiOH simulation is at 0.54 ± 0.07 V and the one of the KOH simulation is at at 0.21 ± 0.06 V . According to Frumkin, when the PZC position is determined using sufficiently diluted electrolyte solutions with ions that lack significant specific adsorbability (such as cations) or by extrapolating to infinite dilution, the resulting PZC values depend solely on the properties of the metal and the solvent used; our results show a strong dependency on the electrolyte composition. Since the supercell is of reduced dimensions, our ion concentration is high for the supercell, resulting in the observed shift in the PZC.
