在这篇文章中，我们首次证明了镍泡沫上支撑的硫化镍纳米片阵列可以用作中性和碱性溶液中析氢反应的廉价三维电催化剂。Ni 3S 2/Ni泡沫是一种廉价、高活性和稳定的水电解电极材料。在中性介质中，电流密度为10和100 mA cm（-2）时，过电位分别为220和396 mV;在碱性介质中，电流密度为10和100 mA cm（-2）时，过电位分别为123和260 mV。版权所有（C）2015，氢能出版物有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
In this communication, we demonstrate for the first time that nickel sulfide nanosheets array supported on Ni foam can be used as an inexpensive three-dimensional electrocatalyst toward the hydrogen evolution reaction in both neutral and basic solutions. The Ni3S2/Ni foam served as an inexpensive, highly active and stable electrode material for water electrolysis. It needs overpotentials of 220 and 396 mV to afford current densities of 10 and 100 mA cm(-2) in neutral media and needs overpotentials of 123 and 260 mV to afford current densities of 10 and 100 mA cm(-2) in basic solutions.
