The present invention relates to a method for preparing a carbon nanofiber composite, and a carbon nanofiber composite prepared thereby. The method for preparing a carbon nanofiber composite provided by the present invention has reduced costs and is economical and efficient compared with a convention method for preparing a carbon nanofiber composite. In addition, the carbon nanofiber composite of the present invention can provide remarkable decomposition performance of organic pollutants, and a carbon nanofiber composite prepared by the preparation method of the present invention can be used in an electrode for an electric double-layer supercapacitor, a fuel cell electrode, a filter, a hydrogen storage material, and the like.

Activated carbon fibers and methods of stabilizing, carbonizing, and activating carbon fibers are disclosed. The activated carbon fibers can be used in filtration, chemical capture, energy storage, and other applications. A method of producing an activated carbon fiber material for filtration or gas adsorption can include melt blowing pitch to form pitch fibers, stabilizing the pitch fibers to form stabilized pitch fibers, carbonizing the stabilized pitch fibers to form carbon fibers, and activating the carbon fibers to form activated carbon fibers with a specific surface area of at least 1900 m.sup.2/g.
