外文摘要：In this study,a novel approach is proposed to achieve the uniformly dispersed Ru nanoparticles with N coordination loaded on three-dimensionally ordered macro/mesoporous carbon(3DOMMC)through simultaneous pyrolysis of Ru3+and cyanamide on 3DOMMC.In an alkaline medium,the synthesized catalysts exhibit exceptional hydrogen evolution reaction(HER)performance.Spe-cifically,Ru-N/3DOMMC demonstrates a significantly low overpotential of 13.8 mV to achieve a current density of 10 mA·cm-2,and it exhibits a mass activity 17.5 times higher than that of commercial Pt/C.The outstanding performance could be attributed to the ultra-high Ru dispersion and more efficient contact between active sites and reactant,which derived from the large specific surface area and interconnective three-dimensionally macro/mesopores of 3DOMMC.
