Much research had been done to investigate electrocatalytic synthesis of ammonia from nitrogen sources such as dinitrogen gas and nitrogen oxides (NOx) due to the much lower energy demand compared to the current industrial method: the Haber-Bosch (H-B) process. Many catalysts with high Faradaic efficiency (FE) and yield rates were since developed. The performance of these catalysts can be further improved by the utilization of flow cells. Flow cells negate the issue of mass transport limitation in a traditional H-cell by continuously circulating fresh electrolyte into the chamber. By engineering the flow cell design, reactions can be done successively, removing the step of extraction.
