This paper provides an overview of the advantages and disadvantages of various types of ionic liquids (ILs) for the catalytic conversion of CO 2. The highlight of this paper is a detailed summary of future improvements and directions for the development of ILs. [Display omitted] The conversion of CO 2 into fuels or valuable chemical feedstock can reduce the consumption of fossil fuels. Ionic liquids (ILs) can be applied as designable catalyst for the catalytic chemical conversion of CO 2 , which can react with different substrates to produce valuable chemicals. This review emphasizes the properties of ILs and the research progress of catalytic conversion of CO 2 into organic carbonates, including the reaction mechanism and the advantages and limitations of various ILs. Modification strategies to enhance the catalytic conversion efficiency of CO 2 are highlighted. Functional groups can be introduced to the anions and cations of ILs to form functionalized ILs, and then multiple active sites are constructed to increase the alkalinity of ILs through synergistic action. However, the phase state of homogeneous ILs limits the continuous conversion of CO 2. Later, new types of supported ILs have been explored for the catalysis of CO 2 , mainly with inorganic or organic carriers. Polymerized ionic liquids can be more stable through chemical bonding and improve the stability of the catalytic system. Furthermore, the challenges and prospects of industrial large-scale application of ILs in the future are pointed out. [ABSTRACT FROM AUTHOR]
