中文摘要：
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.cm-2和15 mA.cm-2电沉积电流密度下制得的电极活性较高,尤以15 mA.cm-2时电极性能更佳,并指出了电还原CO2关键材料的结构特性.
英文摘要：
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 CO 2 were investigated in alkaline solutions using a three-electrode system.These results indicated that the Sn / Cu electrodes prepared at 10 mA.cm-2 and 15 mA.cm-2 showed good activities,while that prepared at 15 mA.cm-2 was even better in activities.The synergetic structure of the Sn / Cu electrode to be beneficial to electrochemical reduction of CO 2 has been pointed out.
