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.
