a Four DFT calculation models with potential active sites for electrochemical production of H2O2. Blue, red, white, and gray balls denote metal, O, H, and C atoms, respectively. b The simulated activity volcano plot for 2-electron ORR path to H2O2. The theoretical equilibrium potential is shown as a gray dashed line. c Illustration showing the effect of Lewis acidity to the electron distribution of adjacent carbon atom.
