“…For example, the addition of Cu nanoparticles to ILs caused their surface to become positively polarized and resulted in increased CO 2 permeance and selectivity [ 72 ]. Different ILs, such as [HMIM][NO 3 ], [OMIM][BF 4 ] or [BMIM][NO 3 ], have been tested with PES supports [ 73 , 74 ] and [BMIM][BF 4 ] with KIT-6 silica support [ 75 ]. The factors that affect the performance of this type of SILMs with Cu nanoparticles have been deeply investigated [ 76 ].…”

A bibliometric analysis based on Scopus database was performed to identify the global research trends related to Supported Ionic Liquid Membranes (SILMs) during the time period from 1995 to 2015. This work tries to improve the understanding of the most relevant research topics and applications. The results from the analysis reveal that only after 2005 the research efforts focused on SILMs became significant, since the references found before that year are scarce. The most important research works on the four main application groups for SILMs defined in this work (carbon dioxide separation, other gas phase separations, pervaporation and liquid phase separations) were summarized in this paper. Carbon dioxide separation appeared as the application that has received by far the most attention according to the research trends during the analysed period. Comments about other significant applications that are gaining attention, such as the employment of SILMs in analytical tasks or their consideration for the production of fuel cells, have been included.

“…Gas separation performances of IL-based composite membranes can be improved by increasing IL contents, but the high-content IL will decrease the mechanical property of the membranes. Adding some inorganic particles or MOFs with better gas separation performances, including SAPO-34, , ZIF-8, , and others, − is a promising strategy to make membrane simultaneously possess high separation performances and great long-term stability. Hudiono et al , reported a novel MMM containing three components, a styrene-based poly(IL), an IL ([Emim][Tf 2 N]) and SAPO-34 zeolite particles for CO 2 separation.…”

The inherent structure tunability, good affinity with CO, and nonvolatility of ionic liquids (ILs) drive their exploration and exploitation in CO separation field, and has attracted remarkable interest from both industries and academia. The aim of this Review is to give a detailed overview on the recent advances on IL-based materials, including pure ILs, IL-based solvents, and IL-based membranes for CO capture and separation from the viewpoint of molecule to engineering. The effects of anions, cations and functional groups on CO solubility and selectivity of ILs, as well as the studies on degradability of ILs are reviewed, and the recent developments on functionalized ILs, IL-based solvents, and IL-based membranes are also discussed. CO separation mechanism with IL-based solvents and IL-based membranes are explained by combining molecular simulation and experimental characterization. Taking into consideration of the applications and industrialization, the recent achievements and developments on the transport properties of IL fluids and the process design of IL-based processes are highlighted. Finally, the future research challenges and perspectives of the commercialization of CO capture and separation with IL-based materials are posed.

Two-dimensional (2D) materials-based membranes show great potential for gas separation. Herein an ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF]), was confined in the 2D channels of MoS-laminated membranes via an infiltration process. Compared with the corresponding bulk [BMIM][BF], nanoconfined [BMIM][BF] shows an obvious incremental increase in freezing point and a shift of vibration bands. The resulting MoS-supported ionic liquid membrane (MoS SILM) exhibits excellent CO separation performance with high CO permeance (47.88 GPU) and superb selectivity for CO/N (131.42), CO/CH (43.52), and CO/H (14.95), which is much better than that of neat [BMIM][BF] and [BMIM][BF]-based membranes. The outstanding performance of MoS SILMs is attributed to the nanoconfined [BMIM][BF], which enables fast transport of CO. Long-term operation also reveals the durability and stability of the prepared MoS SILMs. The method of confining ILs in the 2D nanochannels of 2D materials may pave a new way for CO capture and separation.
