Sustainable ammonia production from nitrate reduction assisted by methanol oxidation using Co@CF bifunctional electrocatalysts

Nitrate pollution threatens water ecosystems. A Cu-based Co@CF catalyst, synthesized via in situ electrodeposition, achieves 95.16% faradaic efficiency and 7.51 mg h −1 cm −2 NH 3 yield by coupling NO 3 RR with MOR, also producing formic acid with 91.74% efficiency.
