Schematic diagram of in operando GC measurement using a three-electrode system

Caption

(a) Schematic diagram of the in operando GC measurement using a three-electrode system. (b) Faradaic efficiency at a specific voltage (−0.25, −0.15, −0.05, 0.05, 0.15, 0.25, or 0.35 V). The error bar reflects the results of three devices. All electrolysis in this system was performed in 1 M NH3 in 5 M KOH solution at 60 °C. (c) The amount (mL) and (d) faradaic efficiency (%) of each produced gas for operating ammonia electrolysis time over 200 min during discharge at 200 mA. (e) Chronopotentiometric profile in the three-electrode configuration system and (f) hydrogen production per power consumption during consecutive discharge at 200 mA.
