Abstract

Here, we reported a highly efficient nitrate electroreduction (NO₃RR) electrocatalyst that integrated alloying and heterostructuring strategies comprising FeCo alloy and Mo_0.82N (FeCo-Mo_0.82N/NC). Notably, the maximum NH₃ Faraday efficiency (FE) of 83.24%, NH₃ yield of 12.28 mg h^-1 mg_cat.^-1, and good stability were achieved over FeCo-Mo_0.82N/NC. Moreover, a Zn-NO₃^- battery assembled with FeCo-Mo_0.82N/NC exhibited a power density of 0.87 mW cm^-2, an NH₃ yield of 14.09 mg h^-1 mg_cat.^-1, and a FE as high as 76.31%.
