Fig. 5

a Volcano-shaped relationship between the adsorption-free energy of oxygenated intermediates (ΔG*OH–*OH) and the theoretical overpotential (η). b Variations of ΔG*OH–*OH on 23 homonuclear M2@NC. c The η of eight promising M2@NC homonuclear DACs are summarized in terms of ΔG*OH–*OH as the activity descriptor.
