a Gibbs free energy change (ΔG) of *OH toward *OH–*OH versus *OH → *O + H+  +e. Data points screened for high-performance homo- and hetero-nuclear catalysts are colored. b Gibbs free energy change (ΔG) of *OH–*OH → *OH–*O + H+ +e − versus *OH–*OH → *OOH + H+ +e. Insets show the schematic configuration of the different intermediates adsorbed on M′M@NC. The white, red, gray, and blue spheres in the atomic models represent H, O, C, and N atoms, respectively.
