“…Figure 2a shows that the specific surface area and pore volume of the adsorbent gradually decreased as the content of ionic liquid increased, because the pore channels and surface of GDX-103 were gradually occupied by the ionic liquid, where the specific surface area of 70%[C 2 OHmim]-[Lys]@GDX decreased to 6.2 m 2 /g and the pore volume decreased to 0.01 cm 3 /g, which indicated that the pore structure of the carrier was almost completely occupied. 51 The pore size distributions of GDX-103 before and after supporting ionic liquid are very similar, as shown in Figure 2b, with the exception that the corresponding pore volumes are smaller. Due to the comparatively inert surface of GDX-103, the ionic liquid fills both the micropores and mesopores and there is no preferential filling phenomenon on the carrier surface.…”

“…This shows that GDX-103 is a suitable choice for ionic liquid dispersion because it not only effectively supports the ionic liquid onto the surface but also increases the effective contact area between CO 2 and the adsorbent, which is conducive to enhancing the mass transfer effect and improving the CO 2 adsorption capacity and rate of the adsorbent. Figure a shows that the specific surface area and pore volume of the adsorbent gradually decreased as the content of ionic liquid increased, because the pore channels and surface of GDX-103 were gradually occupied by the ionic liquid, where the specific surface area of 70%[C 2 OHmim][Lys]@GDX decreased to 6.2 m 2 /g and the pore volume decreased to 0.01 cm 3 /g, which indicated that the pore structure of the carrier was almost completely occupied …”

A decrease in CO 2 emissions is urgently required in the present situation due to the fast growth of carbon dioxide (CO 2 ) in the atmosphere, which has caused a series of global climate issues. This study used an impregnation−evaporation method to immobilize an amino functionalized ionic liquid [C 2 OHmim][Lys] on a chromatographic column filler GDX-103 and create a novel supported ionic liquid. The results showed that the supported ionic liquid with 60 wt % ionic liquid content had the best adsorption performance at 40 °C, and the CO 2 adsorption isotherm showed that the adsorption capacity at 0.1 MPa was 1.29 mmol CO 2 /g sorbent, which was 6 times greater than the adsorption capacity of the pure carrier. The sample with 60% ionic liquid content has an adsorption capacity of 1.02 mmol CO 2 /g sorbent under the condition of CO 2 /N 2 mixed gas with 10% CO 2 content. This is 43 times greater than the adsorption capacity of the pure carrier, and its adsorption performance is stable after three adsorption and desorption cycles. Through the rich porous structure of GDX-103, the ionic liquid is effectively supported and dispersed, which expands the contact area between CO 2 and ionic liquid and enhances the mass transfer of CO 2 . At the same time, CO 2 can be chemically bound to the groups on the anion of ionic liquid and be immobilized, so it has a high selective adsorption capacity of CO 2 , which makes it a great alternative to traditional CO 2 adsorbents.

“…The synthesized nanomaterial exhibited the best adsorption performance of 1.34 mmol/g at 30% IL loading amount, and its CO 2 adsorption capacity of 0.81 mmol/g was retained after eight cycles. In addition, Xu et al 23 compounded aminopolycarboxylate ILs (APC-ILs) with poly-(divinylbenzene) (PDVB) to create a new and highly effective adsorbent for CO 2 capture. It is found that APC-IL@PDVB samples has the highest CO 2 capacity of 1.65 mmol/g and IL utilization ratio of 1.53 mol/mol, furthermore, the APC-IL@ PDVB samples exhibited excellent selectivity and recycling performance.…”

In this study, an amine polycarboxylate ionic liquid with multiple absorption sites, named [P4442]2[IDA], was selected to synthesize a new type of solid adsorbent for CO2 capture with a modified clay mineral AT (attapulgite). A series of experiments of the synthesized adsorbents were performed using a TGA instrument at atmospheric pressure. Different [P4442]2[IDA] loadings and temperatures were evaluated in the CO2 adsorption process, and the maximal amount of CO2 adsorbed on the adsorbent was 1.531 mmol/g with [P4442]2[IDA] loading of 30% at a temperature of 303 K. Note that, after the [P4442]2[IDA] molecules were impregnated onto the modified AT carrier, the utilization efficiency of [P4442]2[IDA] increased nearly three times, compared with pure [P4442]2[IDA]; this result also indicates that the cost of CO2 capture by ionic liquid is reduced by this method. Moreover, multiple analysis methods were used to analyze the composition and the structure of the adsorbent. The experimental data obtained from the CO2 adsorption process were fitted by two different isotherm models and three different kinetic models; the excellent fit of the Freundlich isotherm model and Avrami’s kinetic model indicates that CO2 capture by this adsorbent is the process which dominated by chemical adsorption and coexists with physical adsorption. In addition, the amount of CO2 adsorbed was only little slightly reduced after ten cycles, exhibiting excellent cyclic adsorption performance which is due to the stability of the bond between the [P4442]2[IDA] molecules and the modified AT carrier, as well as the extremely low volatility of the ionic liquid.
