Ni3FeN Nanoparticles Derived from Ultrathin NiFe‐Layered Double Hydroxide Nanosheets: An Efficient Overall Water Splitting Electrocatalyst

Ni3FeN nanoparticles with a particle size of ≈100 nm and a thickness of ≈9 nm are successfully synthesized by thermal ammonolysis of ultrathin NiFe-layered double hydroxide ultrathin nanosheets. The Ni3FeN nanoparticles exhibit excellent catalytic performance and high stability in electrochemical overall water splitting.
