摘要

A highly active and stable catalyst is crucial for the hydrogen evolution reaction (HER). In this study, anovel coral-like Ru/carbon (Ru/C) electrocatalyst was synthesized via a solvothermal approach with theassistance of 8-hydroxyquinoline (8-HQ). This catalyst exhibited excellent performance for the HER inacidic media. The overpotential of the Ru/C catalyst was 41 mV at a current density of 10 mA/cm 2 , theTafel slope was 46 mV/dec, which was only 12 mV/dec higher than that of the Pt/C catalyst (34 mV/dec).Moreover, the Ru/C catalyst exhibited excellent stability. We believe that this novel Ru/C catalyst is aviable substitute for commercial Pt/C catalysts.
