Abstract
Carbon nanofibers (CNFs) containing Ni nanoparticles were synthesized by carbonization of electrospun polyacrylonitrile nanofibers containing NiCl2 followed by low-temperature activation (~325 °C) in an oxygen atmosphere. The surface area of activated CNFs with 0.11 wt.% of the Ni oxide nanoparticles was 654 ㎡/g with increasing nanopores, which is significantly higher than the value for pure CNFs (30 ㎡/g). It was confirmed that the addition of trace amounts of Ni nanoparticles effectively produces a porous structure due to their catalytic role, which can increase the specific adsorption capacity of the activated CNFs without structural deformation.
