Introduction

Generally, ionic liquids (ILs) are defined as those fused salts with a melting point less than 100 °C, with salts with higher melting points referred to as molten salts [16]. As far as we can ascertain, the first truly room-temperature IL discovered was ethylammonium nitrate ([EtNH3][NO3]) reported in 1914 by Walden [41], with a melting point of 12.5 °C [31]. Typical ILs are composed of a large organic cation and an inorganic polyatomic anion or an organic polyatomic anion, showing the high thermal stability, low vapor pressure, wide liquid temperature range, and adjustable physicochemical characteristics [12, 50]. The physicochemical properties of ILs can be easily tuned by changing the type and structure of anions and cations, and once a potential IL satisfying the property specifications is screened, the chemists are required to synthesize it for a given separation task such as the adsorption of toxic gases. Therefore, ILs can be regarded as “designer solvents” in...
