AB - In this study, electrospun nanofibers made of PAN (polyacrylonitrile) were activated through a physical method to obtain an optimized pore structure. In particular, to enhance the surface alkalinity, the activated carbon fibers (ANFs) were impregnated with tetraethylenepentamine (TEPA) with the aid of HNO3. Then, the low level (3,000 ppm) CO2 adsorption capacity for each ANF sample was evaluated. The specific surface area of ANFs increased from 308.4 m2/g to 839.4 m2/g and the total pore volume increased from 7.882 cm3/g to 27.50 cm3/g. Although the TEPA impregnation reduced the specific surface area and pore volume of the ANFs due to blocking of micropores, the HNO3 pre-oxidation enhanced the amino groups tethered, increasing the amine content from 6.42% to 17.19%, and finally, increased the adsorption capacity of CO2. This study showed that the sample 60-ANF-HNO3-TEPA, which was activated for 60 minutes and was impregnated with HNO3 and TEPA, had the best adsorption capacity for low level (0.3%) CO2 (in a binary mixture with N2).
