In response to global energy and environmental issues, development of efficient and robust earth-abundant electrocatalysts for hydrogen evolution reaction is particularly meaningful. In this study, a facile hydrothermal method is developed to synthesize porous CoS2 nanostructures by using sulfur powder and thiourea as sulfur sources on carbon cloths for highly efficient hydrogen evolution reactions. The huge load of CoS2 on carbon cloth，their unique porous nanostructures equiped CoS2 nanomaterials with excellent electrocatalytic properties. The remarkable HER catalytic performance was achieved with -67 mV at a current density -10 mA cm-2 and the Tafel slope 62 mV dec-1 in 0.5 M H2SO4 solution. The overpotential of HER only lost 2 mV after 1000 cycles with remarkable stability. I think this work opens up a low cost and scalable route to fabricate transition metal-based materials for application in electrocatalysis.
