Herein, we report the controlled and direct fabrication of Cu₂O/CuO thin film on the conductive nickel foam using electrodeposition route for the electrochemical reduction of carbon dioxide (CO₂) to methanol. The electrocatalytic reduction was performed in CO₂ saturated aqueous solution consisting of KHCO₃, pyridine and HCl at room temperature. CO₂ reduction was carried out at a constant potential of −1.3 V for 120 min to study the electrochemical performance of the prepared electrocatalysts. Cu₂O/CuO shows better electrocatalytic activity with highest current density of 46 mA/cm². The prepared catalyst can be an efficient and selective electrode for the production of methanol.

用于将二氧化碳电化学还原为甲醇的Cu2O / CuO电催化剂

本文中，我们报道了使用电沉积途径将二氧化碳（CO ₂）电化学还原为甲醇的方法，在导电镍泡沫上控制和直接制备Cu ₂ O / CuO薄膜。在室温下，在由KHCO ₃，吡啶和HCl组成的CO ₂饱和水溶液中进行电催化还原。在-1.3 V的恒定电势下进行120分钟的CO ₂还原，以研究制得的电催化剂的电化学性能。Cu ₂ O / CuO具有更好的电催化活性，最大电流密度为46 mA / cm ²。所制备的催化剂可以是用于生产甲醇的有效且选择性的电极。
