The reaction energy barrier ∆𝐸 of Rx3 is calculated to be 0.29 eV, as can be seen in on Figure . This reaction is crucial for C-N products formation; the anodic potential provides an oxidizing driving force to convert NH3 to NH2, which is attributed to improved C-N formation selectivity. Thus, the kinetics of Rx3 are also investigated, and are shown on Figure . The activation energy barrier is found to be ~ 0.4 eV. This value is neither relatively big nor small, meaning there is a necessity for an oxidizing potential, but it does not have to be large. This fits the fact that optimal conditions were observed at -0.2 V vs Ag/AgCl.
