摘要：
Ammonia is an important chemical and ideal energy vector. Artificial ammonia synthesis through the Haber-Bosch (H-B) process is energy-intensive. In contrast, ammonia is generated from N2 and H2O under mild conditions through the electrocatalytic ammonia synthesis. Ru-based catalyst performs superior activities during the nitrogen reduction reaction (NRR), which has attracted extensive attention. However, its development is limited owing to its scarcity. Therefore, the NRR reaction mechanisms are briefly outlined and a systematic summary of Ru-based electrocatalysts for ammonia synthesis is introduced firstly. Subsequently, it is methodically discussed how the strategies for performance enhancement (structural optimization, surface/interface engineering, defect engineering) of catalysts regulate the active sites or electronic structure and then promote the activity of catalysts. Finally, the remaining challenges of Ru-based electrocatalysts in future are highlighted. This review aims to achieve the usage of the Ru metal effectively through the performance-improving strategies of Ru-based electrocatalysts and provides the theory guidance for the design of the other NRR catalysts. © 2023 Chemical Industry Press.
