title: CoSe2 nanowires array as a 3D electrode for highly efficient electrochemical hydrogen evolution.
abstract: 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.
