Abstract:
Fe, Mo-doped Ni3S2 nanosheets that are derived from NiFe-LDH by structural transformation have been successfully developed. The obtained Fe, Mo-Ni3S2 exhibits a low overpotential of 67 mV to enable a current density of 10 mA cm-2 for the HER and the overpotential for the OER is only 240 mV. Besides, the current density of 10 mA cm-2 can be achieved with a voltage of 1.53 V in a two-electrode hydrolysis device.
