Abstract:
Here, we reported a highly efficient nitrate electroreduction (NO3RR) electrocatalyst that integrated alloying and heterostructuring strategies comprising FeCo alloy and Mo0.82N (FeCo-Mo0.82N/NC). Notably, the maximum NH3 Faraday efficiency (FE) of 83.24%, NH3 yield of 12.28 mg h-1 mgcat.-1, and good stability were achieved over FeCo-Mo0.82N/NC. Moreover, a Zn-NO3- battery assembled with FeCo-Mo0.82N/NC exhibited a power density of 0.87 mW cm-2, an NH3 yield of 14.09 mg h-1 mgcat.-1, and a FE as high as 76.31%.
