Activated carbon fibres with extremely high surface areas (ACFs) were prepared by CO2 re-activation using pitch-based ACFs having an original surface area of 1730 m²/g. The highest surface area of the re-activated ACFs was 2930 m²/g as determined from an αS-plot analysis of the nitrogen adsorption isotherm measured at 77 K. The ACF with the highest surface area showed excellent adsorptivity towards supercritical CH4 and H2. The amounts of CH4 and H2 adsorbed were enhanced by 52% and 30%, respectively, as a result of re-activation. [ABSTRACT FROM AUTHOR] |
