However, the majority of catalysts suffer from low current density and Faraday efficiency. To this end, an efficient catalyst of In/Bi-750 with InO_x nanodots load is prepared on a two-dimensional nanoflake Bi₂ O₂ CO₃ substrate, which increases the adsorption of ^* CO₂ due to the synergistic interaction between the bimetals and the exposure of sufficient active sites. In the H-type electrolytic cell, the formate Faraday efficiency (FE) reaches 97.17% at -1.0 V (vs reversible hydrogen electrode (RHE)) with no significant decay over 48 h. A formate Faraday efficiency of 90.83% is also obtained in the flow cell at a higher current density of 200 mA cm^-2 . Both in-situ Fourier transform infrared spectroscopy (FT-IR) and theoretical calculations show that the BiIn bimetallic site can deliver superior binding energy to the ^* OCHO intermediate, thereby fundamentally accelerating the conversion of CO₂ to HCOOH. Furthermore, assembled Zn-CO₂ cell exhibits a maximum power of 6.97 mW cm^-1 and a stability of 60 h.23:T49f,Bismuth-based catalysts exhibit excellent activity and selectivity for the electroreduction of carbon dioxide (CO2). However, single-component bismuth-based catalysts are not satisfactory for the electrochemical reduction of CO2 to formic acid, mainly due to their high hydrogen production, low electrical conductivity, and small catalytic current density. Herein, we used a coordination strategy to recombine Bi and In at the molecular level to form Bi/In bimetallic metal–organic frameworks (MOFs), which were then calcined to obtain MOF-derived Bi/In bimetallic oxide nanoparticles embedded in carbon networks. Thanks to the synergistic effect of bimetallic components, high specific surface area, suitable pore size distribution, and high electrical conductivity of the carbon network, the material exhibits excellent activity and selectivity for electroreduction of CO2 to formate. In H-type electrolyzers, the formate Faradaic efficiency reaches 91% at −0.9 V (vs RHE) and does not decrease significantly within 48 h. In situ Fourier transform infrared spectroscopy confirms the reaction intermediates and reveals that CO2 electroreduction is dominant by the *OCHO pathway.24:T4c8,Bismuth-based materials are prevalent catalysts for CO2 electroreduction to formate, enduring high hydrogen evolution reactions and inadequate activity and stability. Herein, we reveal that in-situ electrochemical transformation of Cu2BiSx solid solution into Bi/CuxSy heterointerfaces, which can stabilize the intermediates and achieve highly selective and consistent CO2 electroreduction. It shows over 85% Faraday efficiency (FE) of formate with a potential window of −0.8 to −1.2 VRHE (RHE: reversible hydrogen electrode) and a stability above 90% over 27 h in H-type cell at −0.9 VRHE. It maintains more than 85% of FEformate at the current density of −25 to −200 mA·cm−2, and has stability of about 80% of FEformate at least 10 h at −150 mA·cm−2 in flow cell. In-situ Fourier transform infrared (FT-IR) spectroscopy measurement confirms that the preferred route of catalytic reaction is to generate *CO2− and *OCHO intermediates.
