  ABSTRACT: Cobalt sulfide (Co9S8) nanotubes were found to be an electrocatalyst for the hydrogen evolution reaction under alkaline condition. An electrode comprising of Co9S8 nanotubes on a glass carbon electrode (GCE) (mass loading: 0.855 mg·cm-2) produced a cathodic current density of 20 mA·cm-2 at an overpotential of 320 mV. The Co9S8/GCE electrode was stable over 20,000 s during potentiostatic electrolysis. Minor degradation of reduction current after 4000 cyclic voltammetric sweeps suggests the long-term viability under operating conditions. The faradaic efficiency of Co9S8 nanotubes is nearly 100% during the electrolysis of water.
