Abstract AITranslate

Ni3S2@NiMo-LDH composite electrocatalytic material was prepared on a nickel foam substrate through hydrothermal method.The phase composition,microstructure,and electrocatalytic properties of the prepared electrocatalytic material were characterized using X-ray diffractometer(XRD),scanning electron microscope(SEM),and electrochemical workstation.The experimental exresults demonstrate that Ni-Mo-LDH nanospheres are successfully grown on the Ni3S2 nanosheet substrate,obtaining Ni3S2@NiMo-LDH composite electrocatalytic material.The Ni3S2@NiMo-LDH composite electrocatalytic material exhibits an overpotential of 84.7 mV for the hydrogen evolution reaction(HER)at a current density of 10 mA/cm2,and an overpotential of 270 mV for the oxygen evolution reaction(OER)at 20 mA/cm2.The overall water splitting voltage of Ni3S2@NiMo-LDH two-electrode system required at a current density of 150 mA/cm2 is 2.19 V.Compared to the individual Ni3S2 and NiMo-LDH materials,the Ni3S2@NiMo-LDH composite material exhibits superior electrocatalytic properties and excellent stability.
