Solid-State Poly(ionic liquid) Gels for Simultaneous CO2 Adsorption and Electrochemical Reduction

Journal Article


Abstract


  • Managing carbon dioxide (CO2) released from large-scale industrial

    processes is of great importance, yet there remain

    significant technical challenges. Herein, the fabrication of 1-

    mm-thick solid-state electrochemical devices based on poly-

    (ionic liquid) ionogels with embedded electrodes capable of

    both adsorption and electrochemical reduction of CO2 is reported.

    The ionogels are prepared via radical polymerization

    and chemical crosslinking of a vinyl imidazolium trifluoromethanesulfonimide

    ionic liquid monomer in the presence of

    additional ionic liquids (ILs) that act as swelling agents and

    enhance ionic conductivity. The effects of the ILs concentration

    and the degree of crosslinking on the mechanical properties,

    conductivity, and CO2 adsorption of the ionogels are

    investigated. The ionogels are shown to have ionic conductivities

    as high as 0.6 mScm@1. The results of quartz crystal microbalance

    analyses demonstrates that the CO2 adsorption of

    the ionogels reaches up to &22 mgg@1, which is 10-fold

    higher than that of their native ionic liquid. Moreover, the

    ionogels are easily recoverable after CO2 adsorption. The

    flexibility, conductivity, and CO2 capture capacity of this

    system can be controlled by the crosslinking ratio and ionic

    liquid content of the ionogels. This electrochemical device

    has the potential to be used in large scale plants for capturing

    CO2 for further electrochemical reactions.
