a WOR processes via different pathways. La, Al, O, and H are represented by gray, blue, red, and white spheres, respectively. b Free energy diagram of all the three WORs over LaAlO3. c Calculated limiting potentials (UL, left axis) for the metal oxides, and the corresponding formation energies (right axis) under 2e-WOR (electrolyte pH = 11 or 8). d Volcano plots of limiting potential as a function of ΔGOH*.
