Carbon nanotube-based aerogels attract attention due to the high surface area and porosity. In this study, carbon nanotube aerogels were synthesized by carbon nanotubes and chitosan. Chitosan and CNT was dissolved in 1M HCl solution. The Chitosan/CNT mixture were freeze dry for preparing aerogels. Aerogels were carbonized at 200℃, 1 hr, and N2 flow conditions. After carbonized, prepared samples were washed using water and ethanol until neutralization. The structural information of the activated carbons was measured by X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The N2 adsorption-desorption isotherms were measured at 77 K and calculated by Brunauer-Emmett-Teller (BET) equation. The pore size distributions were investigated using non-local density functional theory (NLDFT). |
