In this Letter, we describe the development of a CoSe2 nanowires array on carbon cloth (CoSe2 NW/CC) through a facile two-step hydrothermal preparative strategy. As a novel 3D nanoarray electrode for electrochemical hydrogen evolution, CoSe2 NW/CC exhibits excellent catalytic activity and durability in acidic media. It needs overpotentials of 130 and 164 mV to approach 10 and 100 mA cm(-2), respectively, and its activity is maintained for at least 48 h. This work would open up new avenues for the rational design of a variety of arrayed transition-metal chalcogenide cathodes for technological application toward large-scale hydrogen generation from water.
在本信函中，我们描述了通过简便的两步水热制备策略在碳布上制备二硒化钴纳米线阵列（CoSe₂ NW/CC）的过程。作为一种用于电化学析氢的新型三维纳米阵列电极，CoSe₂ NW/CC在酸性介质中表现出优异的催化活性和耐久性。分别达到10和100 mA cm⁻²时，其过电位分别为130和164 mV，并且其活性至少可维持48小时。这项工作将为合理设计各种阵列化过渡金属硫族化物阴极开辟新途径，以用于从水中大规模制氢的技术应用。
