Massive emissions of CO₂ have caused environmental problems all over the world. The fixation of CO₂ into cyclic carbonates is regarded as an effective way of capturing and utilizing CO₂. Ionic liquid catalysts (ILCs) have received great attention and been employed for catalyzing the above reaction in recent years due to their unique properties. However, there are still a few problems requiring solutions in order to finally find the “ideal catalyst”. Herein, we reviewed a number of recent related literature. The progresses of both homogeneous and heterogeneous ILCs were discussed to find out where we are and which directions to work on. The effects of cations and anions of ionic liquids (ILs), functional groups, reaction phase states, structures of supports, preparation methods of supported ionic liquids (SILs), and interactions between the ILs and supports were investigated systematically. Accordingly, basic principles of designing ILCs for the title reaction are summarized and directions of future investigations are highlighted.

均相和非均相离子液体系统：有望将二氧化碳固定为环状碳酸酯的“理想催化剂”

大量的CO ₂排放已在世界范围内引起环境问题。将CO ₂固定在环状碳酸酯中被认为是捕获和利用CO ₂的有效方法。离子液体催化剂（ILC）由于其独特的性能而近年来受到广泛关注并被用于催化上述反应。但是，仍然存在一些问题，需要解决方案才能最终找到“理想的催化剂”。本文中，我们回顾了许多最新的相关文献。讨论了同质和异质ILC的进展，以了解我们身在何处以及应在哪些方向上开展工作。系统地研究了离子液体（ILs）的阳离子和阴离子，官能团，反应相态，载体的结构，载体上离子液体（SILs）的制备方法以及ILs与载体之间的相互作用的影响。因此，总结了设计用于标题反应的ILC的基本原理，并突出了未来研究的方向。
