The development of c.st-effec.ive, highly effic.ent, and durable elec.roc.talysts has been a paramount pursuit for advanc.ng the hydrogen evolution reac.ion (HER). Herein, a simplified synthesis protoc.l w.s designed to ac.ieve a self-standing elec.rode, c.mposed of ac.ivated c.rbon paper embedded w.th Ru single-atom c.talysts and Ru nanoc.usters (Ac./RuSAc.c. via ac.d ac.ivation, immersion, and high-temperature pyrolysis. Ab initio molec.lar dynamic. (AIMD) c.lc.lations are employed to gain a more profound understanding of the impac. of ac.d ac.ivation on c.rbon paper. Furthermore, the c.existenc. states of the Ru atoms are c.nfirmed via aberration-c.rrec.ed sc.nning transmission elec.ron mic.osc.py (Ac.STEM), X-ray photoelec.ron spec.rosc.py (XPS), and X-ray absorption spec.rosc.py (XAS). Experimental measurements and theoretic.l c.lc.lations reveal that introduc.ng a Ru single-atom site adjac.nt to the Ru nanoc.usters induc.s a synergistic.effec., tuning the elec.ronic.struc.ure and thereby signific.ntly enhanc.ng their c.talytic.performanc.. Notably, the Ac./RuSAc.c.exhibits a remarkable turnover frequenc. (TOF) of 18 s-1 and an exc.ptional mass ac.ivity (MA) of 2.2 A mg-1, surpassing the performanc. of c.nventional Pt elec.rodes. The self-standing elec.rode, featuring harmoniously c.existing Ru states, stands out as a prospec.ive c.oic. for advanc.ng HER c.talysts, enhanc.ng energy effic.enc., produc.ivity, and selec.ivity. A self-standing elec.rode w.th the c.existenc. of Ru single atoms and Ru nanoc.usters is designed for the hydrogen evolution reac.ion (HER). Additional ac.d ac.ivation proc.ss induc.s defec.s, anc.oring more Ru ions on the substrate.
