Glucose-derived carbon sphere supported cobalt phosphide nanoparticles(Co P/C) were synthesized via a concise two-step method. The electrochemical measurement results indicate that the Co P/C prepared at 900 ℃ presents excellent electrocatalytic performance for hydrogen evolution reaction(HER). The overpotential at a current density of 10 m A cm~(-2) is 108 and 163 mV in 0.5 M H_2SO_4 and 1 M KOH, respectively, and maintains its electrocatalytic durability for at least 10 h. This work supplies a new field to challenge the construction of electrocatalysts for HER through using cost-effective carbon supported transition metal phosphides.
