Abstract: The generation of ammonia by electrochemical nitrogen reduction reaction (eNRR) under ambient conditions has been recognized as a promising alternative energy conversion and storage approach to the traditional Haber-Bosch method. Noble metal-based catalysts play a vital role in this electrochemical ammonia synthesis. This review focuses on recent research progress in noble metal catalysts for eNRR in aqueous solutions under ambient conditions. Reaction mechanisms are elaborated from theoretical and computational perspectives, and the synthesis strategies are summarized and analyzed. Finally, the current challenges in exploring high-performance noble metal catalysts are analyzed, and several future research directions are proposed.
