Abstract The conversion of CO 2 into formate through electrochemical methods is emerging as an elegant approach for industrial‐scale utilization in the near future. Although Bismuth (Bi)‐based materials have shown promise thank to their excellent selectivity, limited reactivity remains a challenge. Herein, this study demonstrates significant enhancement ‐to‐formate efficiency Bi by incorporating ruthenium (Ru) atomic species. Ru single atom doped exhibited nearly twofold higher partial current density compared with pure and clusters Bi, while over 95% Faradaic (FE) maintained. Through comprehensive investigations using combined techniques, operando spectroscopy, theoretical calculations, elucidates that presence promotes H O dissociation H* migration sites significantly reducing energy barrier via spillover path. Besides, it constructed Ru–Bi bridge efficient hydrogenation non‐spillover path, which served major mechanism Bi.

Abstract Renewable electricity shows immense potential as a driving force for the carbon dioxide reduction reaction (CO 2 RR) in production of formate (HCOO − ) at industrial current density, providing promising path value‐added chemicals and chemical manufacturing. However, achieving high selectivity stable HCOO density remains challenge. Here, we present robust Bi 0.6 Cu 0.4 NSs catalyst capable regenerating necessary catalytic core (Bi−O) through cyclic voltammetry (CV) treatment. Notably, 260 mA cm −2 , faradaic efficiency reaches an exceptional to 99.23 %, maintaining above 90 % even after 400 h, which is longest time reported density. Furthermore, stability test, was constructed by CV reconstruction achieve efficient . In 20 h has rate 13.24 mmol m s −1 concentration 1.91 mol L energy consumption 129.80 kWh kmol situ Raman spectroscopy reveals formation Bi−O structure during gradual transformation from NBs NSs. Theoretical studies highlight pivotal role modifying adsorption behavior intermediates, further reduces barrier *OCHO conversion CO RR.
