Comparative studies of porous carbon nanofibers by various activation methods |
| 초록 |
In this study, the activated carbons fibers (ACFs) were prepared from polyacrylonitrile-based nanofibers by physical (steam and CO2) and chemical (KOH) activations. The surface and structural characteristics of porous carbons were observed by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. Pore characteristics were investigated by N2/77K adsorption isotherms. Specific surface area of the physically activated carbons were increased up to 1870 m2/g and the porous carbons were found to be mainly composed of mesoporous structures. Chemical activation using KOH produced activated carbons with high specific surface area up to 2500 m2/g, and the micropores were mainly found in the porous carbons. The physically activated carbons showed the mixture of Type I and Type IV, and the chemically activated carbons did mainly Type I from IUPAC classification. |
