Pourbaix diagrams of Ru (a,b) and Ag-Rh (c,d) chemical systems calculated using PBEsol (left panel) and HSE06 (right panel). An aqueous ion concentration of 10−6 M and temperature of 298.15 K are considered for the construction of Pourbaix diagrams. The chemical potentials of ions are retrieved from ASE database. The green and red regions indicate stable and unstable domains of the pH-U coordinate space with respect to the reference solid. The stability domain of H2O is shown with white dashed lines.
