电化学还原CO_(2)制备醇类的电极材料研究

Research on Electrode Materials Used in CO_(2)Electrochemical Reduction to Alcohols

随着全球工业化的快速发展,煤、石油、天然气的大量使用,CO_(2)直接向大气的排放导致了全球的环境问题和能源问题。将CO_(2)转化为甲醇和乙醇等化学原料和燃料可以减少CO_(2)的直接排放,又能达到CO_(2)再循环再利用的可持续发展的目的。故电化学法具有设备和工艺简单、反应温和、规模可大可小等优点而备受关注。而电化学还原CO_(2)的关键是阴极材料的选择和制备。基于此,对近年来用于电化学还原CO_(2)制备甲醇和乙醇等醇类的电极材料的研究进行了回顾和展望。

With the rapid development of global industrialization and the massive use of coal,oil,and natural gas,the direct emission of CO_(2)to the atmosphere has led to global environmental and energy problems.Converting CO_(2)into chemical raw materials and fuels such as methanol and ethanol can reduce the direct emission of CO_(2)and achieve the goal of sustainable development of CO_(2)recycling and reuse.Electrochemical method has attracted much attention because of its advantages of simple equipment and process,mild reaction,and large or small scale.The key of CO_(2)electrochemical reduction is choices and preparation of cathode materials.In this paper,the researches on electrode materials used in CO_(2)electrochemical reduction to prepare alcohols such as methanol,ethanol and so on were reviewed.
