Preparation method of porous carbon structure comprising heteroatom using animal's hair and electrode materials using the same

摘要

The present invention relates to a hetero-element-containing porous carbon structure using human hair, a method for producing the same, and an electrode material using the same. Since the hetero-element-containing porous carbon structure according to the present invention is formed using human hair, the hair can be easily obtained in a natural state and is used as a single precursor containing not only carbon but also various hetero elements, It is possible to avoid the use of various harmful reagents including an external organic precursor including a hetero element for a high quality and an economical method to obtain a high quality porous carbon having a large surface area and excellent conductivity and doped with N and S as a hetero element . Therefore, the above-described synthesis method using hair is very inexpensive and simple, but heterohyso which is naturally available from the hair component provides a porous carbon material excellent in conductivity, which is doped in the structure, and these carbon materials can be utilized as an electrode material or an electrode catalyst. In particular, there is an effect of replacing the existing Pt-based metal as the electrode catalyst of the ORR. Since the Pt-based metal is expensive, it has a problem in that the production cost of the electrode catalyst is drastically increased. The present invention can provide a hetero-element-containing porous carbon structure excellent in efficiency as an electrode catalyst, It is also a material that can be welcomed in terms of environment to utilize resources.
