Method for preparing nitrogen doped multi-nano-channel porous carbon nano structures and its performance in super capacitor applications

摘要

The present invention relates to a method for preparing a nitrogen-doped multi-nanochannel porous carbon nanostructure, and to an application thereof to a super capacitor. The method for preparing a nitrogen-doped multi-nanochannel porous carbon nanostructure according to the present invention comprises the following steps: (1) carrying out electrospinning of a polymer precursor solution containing a mixture of a nitrogen-containing polymer, a template polymer and a solvent; and (2) stabilizing and carbonizing fibers subjected to electrospinning in step (1). According to the present invention, the resultant porous carbon nanostructure can provide a large surface area without an activation process, and thus a relatively simple and cost-efficient process can be carried out. In addition, no harmful gases and compounds are used during the manufacturing process, and a carbon structure containing a high content of nitrogen can be obtained. Further, the capacitor using the porous carbon nanostructure shows high electric capacity.
