Dispersing amino acid ionic liquids (AAILs) in porous supports is an effective method to overcome the viscous and corrosive issues of AAILs. Herein, a facilely synthesized mesoporous polymer—polydivinylbenzene (PDVB) was proposed as the support of AAILs for CO2 capture. A simple AAIL—tetraethylammonium glycinate ([N2222][Gly]) was synthesized and then dispersed in PDVB by physical impregnation. The prepared [N2222][Gly]@PDVB samples were systematically characterized and examined for CO2 capture performance. Owing to the large pore volume and rich mesoporisty of PDVB, the CO2 capacities of [N2222][Gly]@PDVB samples are very impressive, with the highest value of 1.55 mmol/g at 75 °C for 10 vol.% of CO2 balanced in N2. The utilization ratios of dispersed [N2222][Gly] at 75 °C approach the theoretical value of 0.5, suggesting the efficient utilization of [N2222][Gly] for the capture of CO2. The adsorption selectivity and reversibility of [N2222][Gly]@PDVB samples are also very good, justifying their promising application in the capture of CO2 from anthropogenic source.

用于分散氨基酸离子液体和有效捕获人为来源二氧化碳的简便合成介孔聚合物
将氨基酸离子液体 (AAIL) 分散在多孔载体中是克服 AAIL 粘性和腐蚀性问题的有效方法。在此,提出了一种简单合成的介孔聚合物聚二乙烯基苯 (PDVB) 作为 AAILs捕获CO 2的载体。合成了一种简单的 AAIL-甘氨酸四乙基铵 ([N 2222 ][Gly]),然后通过物理浸渍将其分散在 PDVB 中。系统地表征和检查制备的 [N 2222 ][Gly]@PDVB 样品的 CO 2捕获性能。由于大的孔体积和PDVB的丰富mesoporisty中,CO 2的能力[N 2222][Gly]@PDVB 样品非常令人印象深刻,在 75°C 下,对于在 N 2 中平衡的10 vol.% CO 2的最高值是 1.55 mmol/g 。分散的 [N 2222 ][Gly] 在 75 °C 时的利用率接近理论值 0.5,表明 [N 2222 ][Gly] 用于捕获 CO 2的有效利用。[N 2222 ][Gly]@PDVB 样品的吸附选择性和可逆性也非常好,证明它们在人为来源的 CO 2捕获中的应用前景广阔。
