Owing to the rapid depletion of fossil fuels and excessive carbon dioxide (CO2) release, the CO2 capture has been studied extensively. In CO2 capture field, porous solid sorbents need low energy for the CO2 recovery and have low heat capacity. Especially, metal organic frameworks (MOFs) as solid sorbents are attracting attention as materials which have not only a high specific surface area due to its microporous property, but also an excellent CO2 adsorption capacity because they are physisorbents. Although Mg2(dobdc) MOF which is one of the top performing MOFs has 8 mmol/g @ 298K and 1 bar, the MOF encounters the bottle-neck of loss capacity to 80% under humid conditions. Recently, supported amine adsorbents are effective for CO2 capture at low CO2 partial pressures and can be stabilized in water via decoration on the open metal site of MOFs. In addition, hollow fiber can possess high loading of adsorbent and good mass transfer rate. In this study, using a two-step spinning and post-spinning such as conversion and insertion reaction, we demonstrated the synthesis of mmen-Mg2(dobdpc) MOF fiber sorbents from magnesium oxide (MgO) precursors. We confirmed the material property and performance of the sample by XRD, SEM, BET, and CO2 sorption test.
