Abstract Nanoporous activated carbon (NAC) beads that prepared by carbonization of microporous polymer 2,6-di-tert-butyl pyridine beads were subjected to bromination followed by amination to synthesize the NAC derivatives carrying amino groups. Grafted bromine groups, 0.41 mmol of Br per 1 g of NAC, are hydrolytic stable at 100 °С and can be successfully substituted by amino groups. SEM, TEM, and texture studies were shown a nanoporosity decrease. However, the aminated NAC beads maintained a narrow nanopore size distribution and high specific surface area, retaining a spherical shape. These beads were evaluated for capturing CO2 and showed good reversible adsorption capacity. The preparation method can easily be scaled up, and the NAC beads can be used for other adsorption applications where shaped carbon solids with developed nanoporosity are required.

溴化纳米多孔活性炭珠的胺化制备 CO2 吸附剂

摘要 将微孔聚合物2,6-二叔丁基吡啶珠经碳化制备的纳米多孔活性炭(NAC)珠经溴化后胺化合成带有氨基的NAC衍生物。接枝的溴基团，每 1 g NAC 含有 0.41 mmol Br，在 100 °С 下水解稳定，并且可以成功地被氨基取代。SEM、TEM 和纹理研究显示纳米孔隙率降低。然而，胺化的 NAC 珠保持了窄的纳米孔径分布和高比表面积，保持了球形。这些珠被评估用于捕获 CO2 并显示出良好的可逆吸附能力。该制备方法可以很容易地扩大规模，
