A simple hydrothermal method was used to successfully prepare Ni3S2/Ni(OH)2 3D nanosheets on nickel foam.The self-supporting electrode showed excellent catalytic activity of OER and HER in alkaline medium (1mol/L KOH).The overpotential at current density of 10mA/cm2 was 330mV and 290mV,respectively.When the electrode was used as both a cathode and an anode catalyst for water splitting,it also showed excellent catalytic performance with an overpotential of 420mV at 10mA/cm2 and excellent catalytic stability.
