Accelerated electrochemical nitrate-to-ammonia conversion over bimetallic Ni ₂ Mo ₃ N with mechanistic insights

Nickel molybdenum nitride supported on nickel foam (Ni 2 Mo 3 N/NF) was used as a catalyst for nitrate reduction to ammonia (NO 3 − RR). Ni 2 Mo 3 N/NF achieved a high faradaic efficiency of 97.72% and a maximum ammonia yield of 5.55 mg h −1 cm −2 .
