摘要

本文报道了一种高效的硝酸电还原（NO3RR）电催化剂，该催化剂将FeCo合金和Mo0.82N （FeCo-Mo0.82N/NC）合金化和异质化策略结合在一起。NH3的最大法拉第效率（FE）为83.24%，NH3产率为12.28 mg h-1 mgcat。-1，在FeCo-Mo0.82N/NC上具有良好的稳定性。用feo - mo0.82 n /NC组装的Zn-NO3 -电池的功率密度为0.87 mW cm-2， NH3产率为14.09 mg h-1 mgcat。-1， FE高达76.31%。

Construction of a Heterostructured Alloy–Molybdenum Nitride Catalyst for Enhanced NH3 Production via Nitrate Electrolysis

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%.
