Effects of operating parameters and ionic liquid properties on fabrication of supported ionic liquid membranes based on mesoporous γ-Al2O3 supports

Ionic Liquid Selectively Facilitates CO2 Transport through Graphene Oxide Membrane

“…Our MD simulation results show that the nanoconfinement reduces the self-diffusion coefficients of all the gas species investigated, but the selectivity should not be significantly modified due to the nanoconfinement (Table S7). The selectivity of CO 2 /N 2 at 373.15 K is 225, which is more than half that of the value at room temperature, and it is also competitive compared with those other supporting material. − This performance is still above the Robeson upper bound. The permeance of CO 2 in a GO membrane decreases as the temperature increases due to the low sorption enthalpy, which agrees with previous results .…”

Homogeneous and Heterogeneous Ionic Liquid System: Promising “Ideal Catalysts” for the Fixation of CO2 into Cyclic Carbonates

“…Hence SILs could possess both advantages of homogeneous and heterogeneous catalysts, theoretically. To immobilize ILs into supports, both physical methods (such as impregnation method, [58] co-assembly method, [92] sol-gel method, [56] SFD method [54,[93][94] ) and chemical methods (such as covalent grafting method [43] ) were carried out. The physical methods could retain the original properties of ILs but suffered leaching problems.…”

Recent progress in the development of ionic liquid‐based mixed matrix membrane for CO 2 separation: A review

“…Table 3 displays the CO 2 absorption capacity of several ILs from the literature. In recent years, there is a growing interest in acetate‐based ILs such as 1‐butyl‐3‐methylimidazolium acetate ([bmim][Ac]) for CO 2 capture application 148‐151 . This type of IL belongs to the group of carboxylate‐based TSIL.…”

“…Their SILMs displayed excellent CO 2 separation properties with CO 2 permeability ranging from 2147 to 2840 Barrer and CO 2 /N 2 selectivity between 178 and 265. Liu et al 150 prepared the [bmim][Ac]‐SILM using the tubular alumina support. In their work, IL loading in the SILM was controlled by varying the impregnation temperature.…”
