a The isotopic composition of HDER as a function of catalyst composition at 50 mA cm−2. b The isotopic composition of ethylene as a function of catalyst composition at 50 mA cm−2 in a 50% H2O-50% D2O mixture with 1 M KOH. c The hydrogenation pathway contributions at 50 mA cm−2. d Correlation between the ethylene FE and hydrogenation pathway. All the error bars represent standard deviation based on three independent samples.
