摘　　要：用电化学还原法将二氧化碳(CO_(2))转化为高能量密度的多碳化学品最近成为一个研究热点,在所有的电化学还原二氧化碳(ERCO_(2))催化材料中,Cu基材料因为对中间体CO良好的吸附性能表现出较高的C_(2)产物选择性.为此首先介绍了ERCO_(2)反应机理以及常见的反应器类型;再总结了5种代表性的Cu基催化剂(单金属、氧化物衍生、金属有机框架、合金和非金属修饰)及其在ERCO_(2)选择性合成乙醇方面的最新进展;并阐述了Cu基高活性催化剂的设计策略,如缺陷工程、形貌控制、晶面工程以及他们之间的协同效应等;最后展望了高效ERCO_(2)催化剂制备乙醇所面临的挑战和今后的发展方向.Electrochemical reduction of carbon dioxide(ERCO_(2))to produce polycarbonate compounds with high energy density has become a hot research topic recently.Among the catalysts for ERCO_(2),Cu-based materials exhibited high selectivity for C_(2)compounds such as ethanol due to their strong adsorption to intermediate CO.Herein the mechanism of ERCO_(2)reaction and common reactor types were introduced first,then the recent progress of the 5 typical Cu-based catalysts,including single-atom catalysts,metal oxides,metal-organic frameworks,alloys and non-metal modified materials,of selective ERCO_(2)to produce ethanol were summarized.And the strategies to design high efficiency Cu-based catalysts such as defect engineering,morphology control,facet engineering and their synergistic effects were discussed.Finally,the challenges encountered and further development for highly efficient ERCO_(2)catalysts to produce ethanol were prospected.
