离子液体 (IL) 是低熔点有机盐，具有较宽的液相线温度范围，具有可忽略的蒸气压、热稳定性、高离子电导率和大电化学窗口等固有有用特性。作为传统有机溶剂的绿色可回收替代品，离子液体在从水中提取有机物和从溶液中提取金属离子方面显示出了良好的前景。有机化合物的异构体分离、有机化学反应的选择性催化过程以及太阳能电池和其他电化学装置。近年来，离子液体在无机纳米材料合成过程中的优势已被认识并受到越来越多的关注。在这篇简短的综述中，概述了有关使用离子液体作为无机纳米材料反应介质的最新进展，主要集中在（1）离子液体的预组织结构作为多孔无机纳米材料的模板效应；（2）离子液体固有的高电荷和极化性，为金属纳米颗粒创造静电和空间稳定性，并有利于纳米颗粒从水到水不混溶溶剂的相转移。
Ionic liquids (ILs) are organic salts of low melting points with a wide range of liquidus temperature and intrinsically useful characteristics of negligible vapour pressure, thermal stability, high ionic conductivity and a large electrochemical window. As a green recyclable alternative to traditional organic solvents, the ILs have shown promise in the liquid/liquid extraction of organics from water and metal ions from solution. and separating isomeric organic compounds, selective catalytic processes for organic chemical reactions and solar cells and other electrochemical devices. In recent years, the advantages of the ILs in inorganic nanomaterial synthetic procedures have been realized and received more and more attention. In this brief review, the latest developments regarding the use of the IL as reaction medium for inorganic nanomaterials are outlined, mainly focused on (1) the preorganized structure of the IL as template effect for porous inorganic nanomaterials and (2) the intrinsic high charge and polarizability of the IL to create electrostatic and steric stabilization for metal nanoparticles and to favor phase transfer of the nanoparticles from water to water-immiscible solvent.
