Hierarchical Fe-doped Ni3Se4 ultrathin nanosheets are synthesized via solvothermal synthesis and a topotactic selenization process. The prepared (Ni,Fe)3Se4 ultrathin nanosheets supported on Ni foam needed an overpotential of only 225 mV to achieve a current density of 10 mA cm−2 and a small Tafel slope of about 41 mV dec−1.
