Advantages Of Using Immobilized Ionic Liquids in the Electrochemical Conversion of CO2

Dioxide Materials has compiled a review of various works utilizing immobilized ionic liquids that have shown exceptional performance for CO2 conversion. The study is published in a special issue of the Journal of Carbon Research.

These tethered ionic liquids have been incorporated into novel anion ion exchange membranes for CO2 electrolysis, as well as for ionomers that have been incorporated into the cathode catalyst layer, providing a co-catalyst for the reduction reaction. In-fact, using these materials leads to an increase of the cell operating current by a factor of two or more and the Faradaic efficiencies by 20–30%. Work from various research groups are compared. Those utilizing materials from Dioxide Materials boast an obvious technological edge based on their results compiled in the graphical abstract.
