Popis: Co3O4 was synthesized on carbon paper (CP) using a facile method to improve electrochemical nitrate-to-ammonia conversion efficiency. The resulting Co3O4-CP electrode demonstrated an exceptional Faradaic efficiency of almost 100% across a broad range of application conditions, with a peak NH3 yield of 3.43 mmol h−1 cm−2 (2.25 mol gCo−1 h−1).
