The increasing emission of carbon dioxide (CO2) caused by unrestrained consumption of fossil fuel in recent hundred years has created globally ecological
environmental
and social problems. On the other hand
CO2 is also a cheap
abundant and renewable C1-feedstock
which can be converted into alcohols
ethers
acids and other chemicals. Compared to many other CO2 recycle techniques
electrochemical reduction of CO2 is more attractive for its clean and controllable process to produce chemicals under mild conditions. This review summarized recent research progresses in electrochemical reduction of CO2 in ionic liquid (ILs) electrolytes. First
major reactions and mechanism of CO2 electro-reaction in ILs were introduced. Then
scientific challenges of ILs on efficient CO2 activation and conversion were discussed. Finally
the application of new functional ILs should be taken as future research focus in CO2 electrochemical reduction.
