摘要/Abstract

离子液体（ionic liquids，ILs）凭借其优良的物理化学特性以及对环境友好的特性，得到广泛应用，但ILs的高粘度性导致反应后分离困难、可循环利用性低等问题.而负载型功能离子液体（supported functional ionic liquids，SFILs）作为离子液体和多种材料的结合体，有着ILs和负载材料的双重优点，可回收性能高、绿色经济高效，在催化领域有着广泛的应用.主要对近几年几种不同类型的SFILs的制备、反应机理分析及其对反应的影响等研究成果进行了综述，包括负载磁性纳米颗粒的ILs、负载石墨烯、分子筛和有机-金属骨架等类型的ILs.

Ionic liquids (ILs) have been widely used because of their excellent physical and chemical properties, and environment-friendly properties. However, the high viscosity of ILs causes difficulties in post-reaction separation and low recyclability. As the combination of ionic liquids with a variety of solid materials, supported functional ILs (SFILs) have the coupled advantages of ILs and loaded materials. It has a wide range of applications in the field of catalysis because of its high recovery performance, green economy and high efficiency. This paper mainly reviews the recent achievements over SFILs in respects of the preparation of ILs supported on various carriers like magnetic nanoparticles, graphene oxide, molecular sieves, organic-metal skeleton etc., the applications as the heterogeneous catalysts to organic transformations, and the understanding of the catalytic mechanism.
Key words: ionic liquids, carriers, green chemistry, catalysis, environmentally-friendly
