Abstract

Glucose-derived carbon sphere supported cobalt phosphide nanoparticles (CoP/C) were synthesized via a concise two-step method. The electrochemical measurement results indicate that the CoP/C prepared at 900 °C presents excellent electrocatalytic performance for hydrogen evolution reaction (HER). The overpotential at a current density of 10 mA cm−2 is 108 and 163 mV in 0.5 M H2SO4 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.
