Extended Data Fig. 3: Potential axis.
From: Inverse kinetic isotope effects in the oxygen reduction reaction at platinum single crystals
Potential axis showing that the RDeE is equal to the RHE in acid (for example 0.1 M HClO4, pH = 1) but is more negative than the RHE by 51 mV in base (for example 0.1 M NaOH, pH = 13) due to due to the difference in pKa in H2O (14) and D2O (14.87).
