Notes
Conversion between the pH-independent Ag/AgCl (1 M KCl) reference and the pH-dependent reversible hydrogen electrode (RHE) scale is given by: E RHE = E Ag/AgCl (1 M KCl) + 0.197 + (0.059 × pH). In this study, the pH after CO2 saturation was 6.8; hence, −1.8 V [Ag/AgCl (1 M KCl)] corresponds to −1.2 V (RHE).
