本文首次将NiS2NA/CC的前驱体Ni(OH)(2)Na/CC硫化，在碳布上制备了NiS2NA/CC纳米片阵列。作为三维析氢阴极，NiS2NA/CC电极在中性溶液中表现出良好的催化活性和稳定性。需要193 mV和243 mV的过电位才能提供2 mA/cm(2)和10 mA/cm(2)的电流密度。这种电极在碱性溶液中也能有效工作。(C)2014爱思唯尔有限公司。保留所有权利。
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/cm(2), respectively. This electrode also works efficiently in basic solutions. (C) 2014 Elsevier Ltd.
