Although Ru-based materials have been recognized as promising electrocatalysts for hydrogen evolution reaction (HER), further improving the mass activity and guaranteeing the high-throughput H production of the catalysts is of vital importance. Herein, Ru single atoms coupling with ultrafine nanoclusters on hierarchical porous N-doped carbon (NMC-Ru) has been synthesized as economical and effective HER catalysts. Density function theory and the experimental results reveal that the strong electronic coupling effects between Ru single atoms and nanoclusters and unique hierarchical structure enable NMC-Ru with the ultralow overpotential for achieving 500 mA cm in alkaline and acidic conditions. More importantly, the NMC-Ru affords a higher mass activity and a lower cost for generating H than those of commercial Pt/C, justifiably proving its remarkable advantages for industrial use. This work offers precise guidance to design catalysts for high-throughput H production from the in-depth understanding of the electronic coupling effect of coupling active sites.
