The reduction of N2 to NH3 is one of the most influential achievement in the field of heterogeneous catalysis. Ammonia is primarily used for the production of fertilizers and enabled the population growth in the 20th century. Due to the difficulties in activating stable N2 molecule, ammonia is still produced in this century-old Haber-Bosch process in the large centralized plants. The electrochemical NH3 production offers an attractive alternative where the electricity could be used to drive the reaction, enabling decentralized production. However, the field of electrochemical ammonia production is lacking a standardized procedure. Ammonia is often present in the environment and can easily contaminate the experimental data. Coupled with low N2 reduction activity, it is difficult to determine the real source of measured ammonia. Here, rigorous experimental protocol will be presented to address the most common problems in benchmarking the electrochemical ammonia production. Quantitative isotopic measurement is indispensable for benchmarking the electrochemical NH3 synthesis. A successful electrochemical production of NH3 using Li-mediated process will be presented. |
