The electrochemical CO2 reduction reaction (CO2RR) to formate offers a promising pathway mitigate the energy crisis and realize carbon neutrality. Bismuth (Bi), as metal catalyst for CO2RR, is considered have great potential in producing formate, yet hindered low current density selectivity. Herein, we constructed an oxide-derived copper foam substrate (OD-Cu) improve electrocatalytic properties of Bi dendrites loaded on its surface. electrodeposited OD-Cu (Bi/OD-Cu) grows pinecone-like dendrites, exhibiting high faradaic efficiency (FEformate) 97.2% partial ~24 mA·cm−2 at −0.97 V vs. RHE (reversible hydrogen electrode) H-cell. Notably, Bi/OD-Cu electrode demonstrates FEformate 95.8% total close 90 −1.17 neutral flow cell. experimental studies reveal that remarkable CO2RR performance results from electron transfer Cu Bi, which optimizes adsorption CO2•− boosts kinetics. This study emphasizes crucial role engineering strategies enhancing catalytic activity shows possibility porous advancing industrialization production.

A 3D flower-like structure composed of porous bismuth oxychloride (p-BiOCl) nanosheets was synthesized through a hydrothermal process utilizing Bi(NO3)3・5 H2O, cetyltrimethylammonium bromide (CTAB) and LiCl. Powder X-ray diffraction (PXRD) studies confirmed the successful formation p-BiOCl. Scanning electron microscopy (SEM) transmission (TEM) were exploited to identify nanosheet structure. The catalyst appeared as reduced Bi0 at an applied cathodic potential − 0.92 V (vs. RHE (reversible hydrogen electrode)). maintenance Bi structures, controlled by cationic surfactant CTAB, resulted in enhanced electrochemical activity with favorable Tafel slope lower charge resistance. Defects under-coordinated sites oxygen vacancy interconnected structures possess abundant active that further assist activity.
