Ambient NH3 synthesis via electrochemical reduction of N2 over Fe–MnO2 layered nanoflower catalysts

An Fe-doped layered MnO 2 nanoflower catalyst was prepared and used as an eNRR catalyst, which achieved an NH 3 yield of 7.54 μg h −1 mg cat −1 and the highest Faraday efficiency (FE) of 11.02% in 0.1 M Na 2 SO 4 .
