为了研究二氧化碳的吸附行为，我们通过简易聚合诱导胶体聚集(PICA)过程制备了以含氮官能团为骨架的介孔碳材料，其中氮含量随碳化温度的变化而变化。所制备的MCs具有较高的比表面积(例如，974×m2/g)和发达的中孔。碳化温度为800℃的MCS-800样品在25℃时的二氧化碳吸附容量最大，为106 mg/g。我们发现，本研究制备的材料对二氧化碳的捕获效率很高，因为MC中的含氮官能团增强了它们对酸性二氧化碳的亲和力。
To investigate carbon dioxide adsorption behaviors, we prepared mesoporous carbon (MC) materials that incorporated framework nitrogen functional groupsviaa facile polymerization-induced colloid aggregation (PICA) procedure, where the nitrogen content varied as a function of carbonization temperature. The prepared MCs had high specific surface areas (e.g., 974 m2/g) with well-developed mesopores. The highest carbon dioxide adsorption capacity of 106 mg/g at 25 °C was achieved with the MCs-800 sample (carbonization temperature of 800 °C). We found that the materials prepared in this study were highly effective for carbon dioxide capture, because the nitrogenous functional groups in the MCs enhanced their affinities for acidic carbon dioxide.
