Abstract
In this paper, we demonstrate the first preparation of NiS2 nanosheets array on carbon cloth (NiS2 NA/CC) via sulfidization of its Ni(OH)2 NA/CC precursor. As a 3D hydrogen evolution cathode, the NiS2 NA/CC electrode shows excellent catalytic activity and stability in neutral solutions. It needs overpotentials of 193 and 243 mV to afford current densities of 2 and 10 mA/cm2, respectively. This electrode also works efficiently in basic solutions.
