摘　　要：The increasing emission of carbon dioxide （CO2） caused by the unrestrained consumption of fossil fuels in recent hundreds of years, has caused global environmental and social problems. Meanwhile, CO2 is a cheap, abundant and renewable Cl-feedstock, which can be converted into alco- hols, ethers, acids and other value-added chemicals. Compared with the thermal reactions, electrochemical reduction of CO2 is more attractive because of its advantages by using the seasonal, geographical and intermittent energy （tide, wind and solar） under mild conditions. In recent years, taking ionic liquids （ILs） as electrolytes in the CO2 electrochemical reduction reaction has been paid much more attention due to the advantages of lowering the overpotential of CO2 electroreduction and improving the Faradaic efficiency. In this paper, we summarized the recent progresses of electrochemical re- duction of CO2 in ILs electrolytes, and analyzed the reaction mechanism of CO2 reaction in the electrode-electrolyte interface region by experimental and simulation methods. Finally, the research which needs to be highlighted in this area was proposed.The increasing emission of carbon dioxide （CO2） caused by the unrestrained consumption of fossil fuels in recent hundreds of years, has caused global environmental and social problems.
