We tabulate all values of ∆G 1 , ∆G 2 (at pH 6), and ∆G tot for the metals in the 11 333-ABC compositions in Table , to compare to the LCO parent structure where the ∆G 1 to release Co-OH from the (001) surface is 9.40 eV, and ∆G 2 (at pH 6) for Co is -9.68 eV. This yields an overall ∆G = -0.28 eV for Co release from LCO at pH 6.
