Here 𝐶 (mol/L) is the concentration of liquid phase C-N bond products obtain based on previous calibration curve obtained from the NMR (, V (L) is the volume of the electrolyte. n is the number of transferred electrons for a certain product, t(h) is the electrolysis time, which is typically 0.5 h. F= 96485 (A× 𝑠 × 𝑚𝑜𝑙 ), A is the geometric area of the electrode (cm 2 ).
