摘要

The present invention relates to a method for preparing a nitrogen-doped carbon nanostructure using electrospinning and a nitrogen-doped carbon nanostructure prepared by the method, It is possible to produce nitrogen-doped carbon nanostructures through economical and simple processes by electrospinning heterogeneous polymer solutions, removing the core without the use of pests such as acids, and carbonizing in an inert atmosphere without harmful gases such as ammonia Because it is easy to mass-produce. In addition, various types of carbon structures having a high surface area can be obtained by controlling the flow rate ratio of the polymer solutions in the electrospinning, and there is an effect of excellent specific capacitance and long cycle stability. Furthermore, it is environmentally friendly because it does not use other materials such as templates, acid solvents and ammonia gas. Furthermore, the nitrogen-doped carbon nanostructure according to the present invention has an excellent performance as compared with the conventional carbon nanostructure.
