Comprehensive Summary Copper (Cu) is recognized as one of the most efficient metal catalysts that can perform electrocatalytic CO 2 reduction reaction (CO RR) and its surface oxidation state determines pathway. The Cu δ + (0 < 1) species, are well known active sites in RR to produce hydrocarbons oxygenates. However, difficult control, it very easy be reduced 0 under operating conditions. Herein, we report a homo‐hetero doping strategy construct an samarium (Sm) sulfur (S) co‐doping catalyst (Sm x ‐CuS y ) for formic acid (HCOOH). At optimum conditions, Sm delivered high HCOOH Faradaic efficiency (FE) 92.1% at current density 300 mA·cm –2 using 1 mol/L KOH aqueous solution electrolyte, potential was low –0.52 V vs. reversible hydrogen electrode (RHE). S resulted excellent performance owing synergistic effect structure. homo‐doping could effectively adjust electronic structure favor formation abundant species. existence hetero‐Sm species not only stabilize sites, but also increase concentration H ions form favorable catalytic environment generation.
