Abstract:
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 Ru 3+ and cyanamide on 3DOMMC.In an alkaline medium, the synthesized catalysts exhibit exceptional hydrogen evolution reaction (HER) performance. Specifically, 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 ultrahigh Ru dispersion and more efficient contact between active sites and reactant, which derived from the large specific surface area and inter‐connective three‐dimensionally macro/mesoporous of 3DOMMC.
