Electrochemical CO2 reduction has attracted much attention due to its advantages to convert CO2 gas into useful chemicals and fuels. Herein, we have developed prism-shaped Cu catalysts for efficient and stable CO2 electrore-duction by using an electrodeposition method. These Cu prism electrodes were characterized by scanning electron mi-croscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Electrochemical CO2 reduction measurements show improved activities for C2H4 production with high partial current density of -11.8 mA/cm2, which is over four times higher than that of the planar Cu sample (-2.8 mA/cm2). We have demonstrated that the enhanced C2H4 production is partially attributed to the higher density of defect sites available on the roughened Cu prism surface. Furthermore, stability tests show a drastic improvement in maintaining C2H4 production over 12 hours. The enhanced performance and durability of prism Cu catalysts hold promise for future industrial applications.
