摘要

Cu电极较之玻碳（GC）电极，更有利于CO2的电还原反应，而电沉积制备的纳米Cu电极可以进一步提高其电催化还原性能。本文考察了电沉积条件，包括沉积时间、H2SO4浓度、沉积电位、Cu2+浓度等对所制备的纳米Cu电极对CO2电还原反应催化性能的影响。针对该反应优化了纳米Cu电极的制备条件，并用SEM表征了其微观形貌。最后还将制备的纳米Cu电极运用于CO2与环氧丙烷的电合成反应，提高了碳酸丙烯酯的反应产率。

Abstract

Cu electrode is very efficient for electroreduction of CO2，while electrodeposited nano-Cu is much better.With the aim of optimizing the electrochemical catalytic behavior of nano-Cu electrode material toward electrochemical reduction of CO2，the electrodeposition conditions，such as deposition time，H2SO4 concentration，deposition potential and Cu2+ concentration，have been investigated.SEM was used to characterize the morphology of nano-Cu.Finally，the nano-Cu was used to the electrochemical synthesis of propylene carbonate from CO2 and propylene oxide.The investigation indicates that the nano-Cu has greater catalytic ability toward the electrochemical reduction of CO2 and higher yield of propylene carbonate can accomplish by using nano-Cu electrode.
