Pitch-based activated carbon fibers and process for preparing the same. |
摘要 |
Disclosed are improved pitch-based activated carbon fibers containing an oxygen content of about 3% by weight or more based on the whole weight of the pitch-based activated carbon fibers, and process for preparing the same by bringing them in contract with an ozone-containing atmosphere, a hydrogen-peroxide solution or nitric acid. The improved pitch-based activated carbon fibers have an excellent adsorptive capacity.
