Abstract
AbstractThe search of alkaline HER electrocatalysts with high performance have attracted great research attentions in recent years. For the construction of the electrocatalysts, a stable conductive substrate is generally required to the uniform distribution of the catalytic materials, where carbon‐based materials are widely utilized. Herein, porous carbon skeletons were prepared after the annealing treatment of Al‐porous coordination polymers with high specific surface area as the substrates for the growth of Ru nanoparticles via wet chemical reduction. The obtained electrocatalysts show a low overpotential of 39 mV at a current density of 10 mA cm−2 and a small Tafel slope of 26 mV dec−1 in 1 M KOH, outperforming the commercial Pt/C. The present work may provide new insights for the design of economy and high‐efficiency electrocatalysts for hydrogen production.
