Abstract As the demand for cleaner energy becomes a paramount objective of sustainable development, advancement cutting‐edge engineered materials wide range applications increasingly vital. Tailoring catalyst properties through precise design and electronic state tuning is essential adapting these to large‐scale applications. Given this, an effective fine‐tuning (EFT) strategy presented optimize structures single‐atom Zn site Ru species, synergistically enhancing both electrocatalytic oxygen reduction reaction (ORR) hydrogen evolution (HER). Benefiting from interaction between species anchored on hierarchically layered nanosheets isolated atoms (Ru@Zn‐SAs/N‐C), exhibits superior ORR HER activities compared benchmark Pt/C catalyst. X‐ray absorption spectroscopy density functional theory (DFT) calculations confirm novel EFT effect single that enables Ru@Zn‐SAs/N‐C approaches optimal scaling relation * OOH OH, breaking universal limitation. Additionally, G H* value positions near apex theoretical volcano model. This work provides innovative avenue regulating localization catalytic active centers by virtue carbon substrate offers valuable insights designing high‐efficiency electrocatalysts.
