| 摘 要： | 采用电镀法制备了In/Cu、In/Fe电极.用电化学测试方法考察了上述电极对CO2在0.2 moL/L的KHCO3溶液中还原反应的电催化活性,并对反应主要产物及电流效率进行分析.实验结果表明,基体上电镀铟有利于CO2的电催化还原,电还原产物主要是甲酸;在几种电极中,In/Cu电极的电催化活性最高,在-1.8 V时获得甲酸的电流效率为32.2%.最后展望了基体电镀的研究方向.

| Abstract: | In this study,In/Cu and In/Fe composite electrode were prepared by the technique of electroplating.By using electrochemical measurement,the electrocatalytic activity of above electrodes for the reduction of CO2 in 0.2 mol/L KHCO3 was studied.The major product of the reaction and current efficiency were analyzed.It is shown that: indium plating on the base was conducive to electrocatalytic reduction of CO2,and formic acid was the main product of electrocatalytic reduction;in all electrode,the In/Cu composite electrode had the highest electrocatalytic activity.The current efficiency of formic acid at-1.8 V was 32.2%.Finally,research interests relevant to electrocatalytic on the base were presented. |
