In this work, carbon nanofibers were successfully expanded intercalating KOH followed by thermal treatment in the different KOH/carbon nanofibers ratios. The aim was to improve the CO2 capture properties of the carbon nanofibers by increasing the microporosity of carbon nanofibers. The influence of thermal treatment on the pore structures of carbon nanofibers were investigated by N2 full isotherms, XRD, SEM, and TEM. The CO2 capture capacity was measured by CO2 isothermal adsorption at 298 K and 1 bar. From the results, it was found that the KOH/carbon nanofibers ratio had a major influence on CO2 capture properties and textural properties of carbon nanofibers. The specific surface area and total pore volume, and pore size of the carbon nanofibers increased after thermaltreatment. |
