Low-temperature pyrolysis enables FeNi3 nanoparticle implanted N-doped carbon nanosheets as an efficient bifunctional electrocatalyst for overall water splitting

The electrocatalyst FeNi 3 /NCS was prepared via the low-temperature pyrolysis of the melamine tube@FeNi-LDH heterostructure, which delivered impressive activity and stability towards water splitting with a low cell potential of 1.53 V at 10 mA cm −2 .
