摘要： The present disclosure relates to a metal nanoparticles impregnated activated carbon fiber for removing harmful substances, and a method of manufacturing the same. A method of manufacturing a metal nanoparticles impregnated activated carbon fiber for removing harmful substances according to the present disclosure includes an activation step of manufacturing an activated carbon fiber by heat-treating a precursor including a waste carbon fiber under a mixed atmosphere of activation gases including water vapor, carbon monoxide, nitrogen, argon, helium, or combinations thereof, and a metal containing step of containing metal in the activated carbon fiber. According to the present disclosure, a carbonization process is unnecessary since a precursor including the waste carbon fiber is used, and the metal nanoparticles impregnated activated carbon fiber may have remarkably improved adsorptive power compared to an activated carbon fiber with the same specific surface area by controlling the micropore distribution.
