摘要

A molten salt process was developed to prepare CoP nanoparticles(NPs) embedded,N,P co-doped carbons with the combination of hand milling and high temperature carbonization.The characterization results implied that the as-prepared samples possessed mesoporous structures.Moreover,the mass ratios of the precursors affected the crystalline structures and the porosities of the final electrocatalysts.The as-prepared catalysts exhibited excellent electrocatalytic performances towards hydrogen evolution reaction(HER) under acidic and alkaline conditions.The as-prepared samples were designed as GxMyCoz,where x,y and z meant the amounts of glucose,melamine and CoCl2,respectively.The optimum sample of G6.0M2.0Co5.0 showed the best HER property with a low onset overpotential and a small Tafel slope,as well as excellent electrocatalytic stability.
