摘　　要：研制纳米薄膜合金电极 (Sb Pb Pt/GC电极 )用于二氧化碳电催化还原。运用循环伏安、电化学原位红外反射光谱和微电极技术对二氧化碳的电还原过程和还原产物进行研究。结果表明 :二氧化碳在此电极上的起始还原电位为 - 0 43V ,主要还原产物为有机羧酸。The reduction process of CO2 on Sb-Pb-Pt/GC electrode prepared by electrochemical co-deposition method was studied with cyclic voltammetry and in-situ FTIR spectroscopy.The results demonstrated that the prepared Sb-Pb-Pt/GC exhibited high activity for CO2 reduction. The onset potential of CO2 reduction was measured at -0.43 V and the main products of reduction were acid species as determined with in-situ FTIR.
