英文摘要：

Heterogeneous systems containing ionic liquids （ILs） with gases and solvents extend the acpplications of ILs in absorption, extraction and heterogeneous catalysis. In recent years, the surface/interfacial properties and surface/interfacial structures of ionic liquids have been widely studied, because they are important due to their remarkable effects on heterogeneous reactions and separation efficiency. In this article, the surface/ interfacial tension, as well as the surface/interfacial structures of ILs and their mixtures with water and organic solvents are summarized. The research methods, objectives and results are introduced. The relationship between surface/interfacial tension and surface/interfacial structures is elucidated. Finally, the exiting problems and development prospects of the studies on surface/interfacial properties and surface/interfacial structures of ILs are discussed.
