Abstract Bismuth‐based materials have emerged as promising catalysts in the electrocatalytic reduction of CO 2 to formate. However, reasons for reconstruction Bi‐based precursors form bismuth nanosheets are still puzzling, especially formation defective sites. Herein, we prepare with vacancy‐rich defects (V‐Bi NS) by rapidly reconstructing Bi 19 Cl 3 S 27 under negative potential. Theoretical analysis reveals that introduction chlorine induces generation intrinsic electric field precursor, thereby increasing electron transfer rate and further promoting metallization trivalent bismuth. Meanwhile, experimental tests verify has a faster than . The formed V‐Bi NS exhibits up 96 % HCOO − Faraday efficiency 400 mA cm −2 partial current densities, its electrochemical active surface area normalized formate density yield 2.2 times higher those intact (I‐Bi NS). Density functional theory calculations indicate vacancies electron‐rich aggregation reduce activation energy *CO radicals stabilize adsorption key intermediate *OCHO, thus facilitating reaction kinetics production.

Electrochemical carbon dioxide reduction reaction (CO2 RR) to produce valuable chemicals is a promising pathway alleviate the energy crisis and global warming issues. However, simultaneously achieving high Faradaic efficiency (FE) current densities of CO2 RR in wide potential range remains as huge challenge for practical implements. Herein, we demonstrate that incorporating bismuth-based (BH) catalysts with L-histidine, common amino acid molecule proteins, an effective strategy overcome inherent trade-off between activity selectivity. Benefiting from significantly enhanced adsorption capability promoted electron-rich nature by L-histidine integrity, BH catalyst exhibits excellent FEformate unprecedented windows (>90 % within -0.1--1.8 V >95 -0.2--1.6 versus reversible hydrogen electrode, RHE). Excellent performance can still be achieved under low-concentration feeding (e.g., 20 vol.%). Besides, extremely low onset -0.05 VRHE (close theoretical thermodynamic -0.02 ) was detected situ ultraviolet-visible (UV-Vis) measurements, together stable operation over 50 h preserved ≈95 partial density 326.2 mA cm-2 at -1.0 .
