Activated carbon fibers (ACF) were prepared from liquefied wood through steam and KOH activation. The results showed that the specific surface area and pore volume of steam- activated ACF (ACF-S) were directly related to the activation temperature. The ACF activated by KOH (ACF-KOH) have more small micropores (<0.7 nm) in addition to more mesopores in the range of 2-4 nm, compared with ACF-S. The ACF-KOH had more oxygenated functional groups on their surfaces than the ACF-S. ACF showed good charge propagation and higher adsorption properties.
