Gas Transport Properties

In this paper have been considered gas transport properties of porous membranes immobilized by 1-butyl‑3-methylimidazolium tetrafluoroborate (bmim [BF4]) and 1-butyl‑3-methylimidazolium acetate (bmim [ace]) toward CH4, CO2 and H2S. Have been investigated transport features of individual gases as well as theirs binary mixtures CO2/CH4 and H2S/CH4. It has been stated that for binary gas mixtures the highest efficiency of acidic gases separation is achieved on membranes containing bmim [ace]. It has been shown experimentally that for a membrane operating according to mechanism of simplified transport, the separation factor increases with diminishing of concentration for penetrant fixed by ionic liquid.

In this work, two new redox-active ionic liquids, one based on 2,2,6,6-tetramethylpiperidine-N-oxide and the other based on 4,4′-bipyridine, are synthesized and characterized. A ferrocene-based redox-active ionic liquid is used for referencing the results. All ionic liquids are formed via salt-metathesis from halogenate to bis(trifluoromethylsulfonyl)imide. Their fundamental thermal characteristics are assessed with differential scanning calorimetry. While the imidazolium ionic liquids show no melting point, the phase transition is well observable for the viologen-based ionic liquid. The properties of the neat redox-active ionic liquids and of binary mixtures containing these ionic liquids (0.1 m) and 1-butyl-1-methyl pyrrolidinium-bis(trifluoromethylsulfonyl)imide have been investigated. Finally, the use of these binary mixtures in combination with activated carbon-based electrodes has been considered in view of the use of these redox-active electrolytes in supercapacitors.

Energy Storage Material

As a new environmentally friendly solvent, ionic liquids have been investigated widely. The lack of physico-chemical properties data of ionic liquids has become a bottleneck that restricts their applications. In this study, the investigation of the density for binary mixtures of CnpyNTf2 (n = 2, 4, 5) and methanol is measured using Westphal balance. This study would be very important for the application of binary mixtures of ionic liquid and methanol in developing new energy storage material.
