| 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 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. |
