The CO2 removal from air/gas is being crucial issue as it is most responsible greenhouse gas for global warming. There are many techniques developed for CO2 capture including physical adsorption, chemical adsorption, cryogenic distillation and membrane adsorption. In this work we established flexible PAN/MOF fibers for CO2 capture with high CO2 adsorption capacity and high CO2/N2 selectivity. Two MOFs with different percentage were used for making of PAN/MOF nanofiber membrane by using crystallization. CO2 and N2 adsorption isotherms were measured by using volumetric apparatus (Belsorp mini II) at the pressure of 0-1 bar and temperature 298K. The as-prepared PAN/MOF fibers showed excellent CO2 adsorption capacity and showed high selectivity compared to the pure MOFs used. the stability of MOF/PAN fiber were confirmed by comparing CO2 adsorption capacity before exposing and after exposing to humid air and acid gases. |
