METHOD FOR PREPARING CARBON NANOFIBER COMPOSITE AND CARBON NANOFIBER COMPOSITE PREPARED THEREBY

摘要

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.

1. A method for preparing a carbon nanofiber composite, comprising:
preparing a spinning solution by mixing a material of a carbon fiber precursor, titanium dioxide (TiO2), and a solvent; preparing a carbon nanofiber by electrospinning the spinning solution; heating the carbon nanofiber to stabilize; heating the stabilized carbon nanofiber in an inert atmosphere to carbonize; hydrothermally treating the carbonized carbon nanofiber in an aqueous alkaline solution to extend the titanium dioxide (TiO2) from the inner part to the outer part of the carbon nanofiber into a titanate nanotube shape; and post oxidizing the hydrothermally treated carbon nanofiber.
