Preparation of Nanosheet-Like Fe-Ni3S2 Catalyst and Electrocatalytic Activity for Oxygen Evolution Reaction
We reported the synthesis of Fe-doped Ni3S2 nanosheets through hydrothermal method using NF as the substrate and Ni source.The structure and morphology of a series of catalysts were characterized with XRD,SEM and Raman,and the oxygen evolution activities were tested.Fe-doped Ni3S2 exhibits a significantly-improved activities compared to Ni3S2.Fe-Ni3S2-1 shows the best OER catalytic activity with low overpotential of 231 mV and 275 mV at 10 mA·cm-2 and 100 mA·cm-2 and Tafel slope of 31.3 mV·dec-1,and good stability.
