摘　　要：综述了近年来离子液体介质中CO2电活化合成有机碳酸酯的研究进展,着重概述了电催化合成碳酸二甲酯(DMC)和环状碳酸酯的研究现状,并简述了CO2间接电活化和直接电活化技术,以及反应介质、电极材料等因素对反应产物的影响,对电催化还原CO2的关键技术和今后研究重点进行了探讨。离子液体具有不易挥发、可循环使用、导电性好、对CO2有较高溶解度等优点,在CO2固定和有机资源化研究中日益受到重视。电化学作为一种环境友好的绿色合成新技术,在CO2有机资源化方面有很好的应用前景,对缓解日益严峻的温室效应、实现CO2的资源化利用具有十分重要的现实意义。In this paper,research progress in the electrochemical activation of CO2 for the synthesis of organic carbonate in ionic liquids have been reviewed, with the focus on the synthesis of DMC（dimethyl carbonate） and cyclic carbonate. The technology of direct and indirect activation of CO2 and the differences of products from different reaction media and electrode materials are briefed. The key technology for the electrocatalytic reduction of CO2 and the research emphasis in the future is also discussed. Ionic liquids have attracted more and more attentions in the study of CO2 fixation and organic sources utilization because of their excellent properties,such as low vapor pressure,high ionic conductivity,easy recycling and high solubility of CO2. Electrochemistry is a novel,environmentally friendly synthesis technology. It has important practical significance to alleviate the increasingly serious greenhouse effect and to motivate the resources utilization of CO2.
