Tóm tắt

Ammonia is an alternative hydrogen storage material and a promising source of sustainable clean energy. The lack of a mechanistic understanding of ammonia electrooxidation hinders the efforts to overcome the slow kinetics of the anode reaction in direct ammonia fuel cells. Herein, we use surface-enhanced Raman spectroscopy to study the electro-decomposition of ammonia on the Au surface. We observe three key reaction intermediate species of *NH
