Abstract
Here, we reported a highly efficient nitrate electroreduction (NO 3 RR) electrocatalyst that integrated alloying and heterostructuring strategies comprising FeCo alloy and Mo 0.82 N (FeCo-Mo 0.82 N/NC). Notably, the maximum NH 3 Faraday efficiency (FE) of 83.24%, NH 3 yield of 12.28 mg h –1 mg cat. –1, and good stability were achieved over FeCo-Mo 0.82 N/NC. Moreover, a Zn-NO 3 – battery assembled with FeCo-Mo 0.82 N/NC exhibited a power density of 0.87 mW cm –2, an NH 3 yield of 14.09 mg h –1 mg cat. –1, and a FE as high as 76.31%.
