Abstract

Abstract:

When ionic liquids are confined in low-dimensional (LD) nano-spaces, the thermal motion of molecules will be greatly limited, resulting in significant differences in the structures and properties compared with three-dimensional bulk ionic liquids. At the same time, the external conditions such as electric fields, magnetic fields and temperatures, as well as factors like the size of the confined nano-space, the physicochemical properties and geometric morphology of the confined surface could also greatly affect the structures and physicochemical properties of LD nanoconfined ionic liquids. In this paper, based on the latest research progress of LD nanoconfined ionic liquids, the experimental and theoretical methods suitable for LD nanoconfined ionic liquids systems are introduced. The dynamic regulation mechanism of LD nano-spaces on the structures and hydrogen bonding networks of confined ionic liquids is also summarized. Moreover, the thermodynamic properties, physicochemical properties and structural phase transition of different LD nanoconfined ionic liquids systems are discussed. Furthermore, the applications of LD nanoconfined ionic liquids systems in gas separation, confined catalysis and energy storage of supercapacitors are combed. Finally, the prospects and challenges of LD nanoconfined ionic liquids are discussed.

Key words: ionic liquids, LD nano-confinement, thermodynamic properties, nanostructure, gas separation
