Coal tar pitch containing finely dispersed KOH was spun centrifugally, followed by stabilization through heating to 330°C under a (1:1) mixture of air and CO 2 and carbonization/activation by heating to 850°C under CO 2 . The activated carbon fiber obtained possessed of a specific surface area of 491 m 2 g −1 and contained ca. 2% of K as K 2 CO 3 over...
Preparation of an antibacterial activated carbon fiber with mesopores was attempted. Phenolic resin containing cobalt as an activation catalyst and silver as an antibacterial agent was spun, stabilized, carbonized and activated in steam. The number of the metal particles increased with as activation proceeded and reached to 100–200 nm in diameter at the largest. The activated carbon fiber with 72...
Preparation of an activated carbon fiber containing mesopores was attempted by catalytic activation using cobalt. Phenolic resin and cobalt-acetylacetonate were mixed intimately, spun, cured, carbonized at 900 C in nitrogen and finally activated at 750 900 C in steam. The carbon fibers with the cobalt contents of 38 ppm and 100 ppm were prepared together with a fiber without cobalt as a reference...
