4 Figure 2 Potential-pH Stability Regimes for TMCs as a Function of Parent Metal Oxygen Binding Energy The dashed lines represent typical potential ranges for various electrochemical reactions. The actual electrocatalyst stability should also depend on the overpotentials required for each reaction. Reprinted from Kimmel et al.,12 with permission. Copyright 2014, American Chemical Society.
