摘要
CO2电还原技术在降低"温室效应"、缓解能源危机及消除密闭环境的CO2等方面都有很重要的意义。综述了金属电极在水溶液、有机溶剂以及熔融体中电还原CO2的研究现况,包括各类金属在电还原CO2过程中所表现出的反应活性以及生成相应产物的反应机理;介绍了电极、温度、压力、电极电位和电解质等因素对金属电极电还原选择性及法拉第电流效率的影响;展望了CO2电还原的未来研究方向及应用前景。
The technology of electrochemical reduction of CO2 is significant for reducing greenhouse effect, relieving energy crisis and eliminating CO2 in spacecraft or submarine. In this paper, the electrochemical reduction of CO2 by various metal electrodes in aqueous solution, organic solvent and molten salt media is reviewed, which includes reaction activity and mechanism of every kind of metal electrodes. The effect of electrode, temperature, pressure, electrode potential and electrolyte on the selective and Faradaic efficiency is introduced. The research and application prospective of the electrochemical reduction of CO2 are discussed.
