Abstract Electrochemical reduction of NO not only offers an attractive alternative to the Haber–Bosch process for ambient NH 3 production but mitigates the human‐caused unbalance of nitrogen cycle. Herein, we report that MoS 2 nanosheet on graphite felt (MoS 2 /GF) acts as an efficient and robust 3D electrocatalyst for NO‐to‐NH 3 conversion. In acidic electrolyte, such MoS 2 /GF attains a maximal Faradaic efficiency of 76.6 % and a large NH 3 yield of up to 99.6 μmol cm −2 h −1 . Using MoS 2 nanosheet‐loaded carbon paper as the cathode, a proof‐of‐concept device of Zn‐NO battery was assembled to deliver a discharge power density of 1.04 mW cm −2 and an NH 3 yield of 411.8 μg h −1 mg cat. −1 . Calculations reveal that the positively charged Mo‐edge sites facilitate NO adsorption/activation via an acceptance–donation mechanism and disfavor the binding of protons and the coupling of N−N bond.
