Abstract (en)
The present invention is related to highly porous carbon fibers, to a process of manufacturing such highly porous carbon fibers based on fast carbonization of carbon precursor fibers, and to the use of such highly porous carbon fibers. The process of manufacturing highly porous carbon fibers according to the present invention comprises a stabilization step, wherein carbon precursor fibers are heated in an oxidizing or non-oxidizing atmosphere at temperatures in the range of from 200 to 500°C, and a pyrolysis step, wherein the such treated carbon precursor fibers are heated in a non-oxidizing atmosphere at temperatures above those of the stabilization step via laser induced heating, microwave heating, or assisted plasma heating, wherein the heating rate in the pyrolysis step is from 5 to 500 K/s, respectively. The obtained highly porous carbon fibers have a surface area in the range of from 100 to 2500 m 2 /g, and a pore diameter in the range of from 0.1 to 10 nm. The highly porous carbon fibers according to the present invention are ideally suited as a composite material, as an electrode material and/or an electrode coating, as an adsorbent, as a filtration medium, as a catalyst support. Moreover, the highly porous carbon fibers according to the present invention are particularly applicable in charge storage, gas storage, filtration and adsorption devices.
