Abstract
Abstract Ruthenium (Ru)‐based electrocatalysts as platinum (Pt) alternatives in catalyzing hydrogen evolution reaction (HER) are promising. However, achieving efficient reaction processes on Ru catalysts is still a challenge, especially in alkaline media. Here, the well‐dispersed Ru nanoparticles with adjacent Ru single atoms on carbon substrate (Ru 1,n ‐NC) is demonstrated to be a superb electrocatalyst for alkaline HER. The obtained Ru 1,n ‐NC exhibits ultralow overpotential (14.8 mV) and high turnover frequency (1.25 H 2 s ‐1 at −0.025 V vs reversible hydrogen electrode), much better than the commercial 40 wt.% Pt/C. The analyses reveal that Ru nanoparticles and single sites can promote each other to…
