Fig. 3. Scaling relations between the adsorption energies of *O, *OH and *OOH (a) under vacuum, and (b) solvated. In each panel linear fits (black) and their equations are provided. Top: *OH vs. *O; middle: *OOH vs. *O; bottom: *OOH vs. *OH. The red dashed lines in (a) are from ref. 11 and show that while ΔGvacO and ΔGvacOH behave normally (top), ΔGvacOOH (middle and bottom) causes large deviations in scaling relations. In (b) solvation restores the scaling relations broken under vacuum by making the slopes approach the ideal values of 0.5 and 1.
