摘要: 采用电沉积法制备Sn/Cu电极,由SEM观察并研究了电沉积电流密度对电极形貌的影响. 在碱性三电极体系中考察了Sn/Cu电极对析氢、CO2还原的影响,发现10 mA/cm2和15 mA/cm2电沉积电流密度下制得的电极活性较高,尤以15 mA/cm2时电极性能更佳,并指出了电还原CO2关键材料的结构特性.

Abstract: The Sn/Cu electrodes were prepared by electroplating method and their morphologies under different galvanization current densities were determined by SEM. In alkali, the effects of Sn/Cu electrodes on the activities towards hydrogen evolution and electrochemical reduction of CO2 were investigated in alkaline solutions using a three-electrode system. These results indicated that the Sn/Cu electrodes prepared at 10 mA/cm2 and 15 mA/cm2 showed good activities, while that prepared at 15 mA/cm2 was even better in activities. The synergetic structure of the Sn/Cu electrode to be beneficial to electrochemical reduction of CO2 has been pointed out.

Key words: Sn/Cu, electrode, electrochemical reduction of CO2
