Abstract With the development of social economy and the expansion of human activities, the concentration of CO₂ in the atmosphere is increasing day by day, and it brings many environmental pollution problems, hence, developing efficient and sustainable techniques for CO₂ conversion is of utmost importance. Based on the electrocatalytic reaction mechanism, a series of CuO/CeO₂ nanorods were fabrication for enhancing the electrochemical reduction of carbon dioxide. The optimized CuO/CeO₂-2 (mol_CeO₂:mol_CuO= 2%) electrocatalyst needed the potential of -0.99V vs. RHE to achieve the current density of 20mA/cm², and displayed the highest FE_C2H4 of 46 % at the potential of -1.08V vs. RHE. The decent property is attributed to large surface area, rough surface, and synergistic effect between CuO and CeO₂, thereby enhancing reaction activity sites and electron transfer efficiency. The study will provide theoretical guidance for the design and optimization of CuO-based composites for efficient CO₂ conversion.
