Electrochemical nitrogen (N-2) reduction has become as an energy-saving and eco-friendly alternative to Haber-Bosch processes for sustainable ammonia (NH3) synthesis at ambient. In recent years, the synthesis of NH3 from N-2 and water (H2O) in aqueous media is one of the most attractive topics in the field of electrochemistry. To date, to achieve both high catalytic performance and selectivity, the enhancement of activity is usually attributed to the high specific surface area, unique facet structure, enhanced conductivity, and even unclear synergistic effects. However, the importance of defec...
