摘要

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 ℃ presents excellent electrocatalytic performance for hydrogen evolution reaction (HER).The overpotential at a current density of 10mA cm-2 is 108 and 163mV in 0.5M 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.
