Outline of Final Research Achievements

The introduction of various defects, such as edges and hetero atoms, is essential to dramatically improve the properties of carbon materials such as graphene. However, in the reporeted methods, various types of defects are introduced, resulting in complicated structures, and the relationship between structure and properties was unclear. In this study, we attempted to synthesize nanocarbon materials with different edge structures, heteroatoms, and five-membered rings, and established a method for structural analysis of the edges and the other defects in carbon materials and detailed analysis of the reaction mechanism. Through this research, we have published 7 papers. We have presented 22 conference presentations. Besides, we submitted 4 patent applications.

炭素材料

Academic Significance and Societal Importance of the Research Achievements

グラフェンなどの炭素材料材料の特性の飛躍的向上には、エッジやヘテロ元素などの種々の欠陥導入が必要不可欠である。しかし既存の導入法では、複数種の欠陥が導入され構造が複雑化してしまい、構造と特性の関係が不明確であった。本研究で、エッジ構造やヘテロ元素、5員環を選択的に導入したナノ炭素材料の合成方法や、分析方法を確立したことにより、今後さらに多種類の構造制御された炭素材料の合成やより精度の高い構造解析につながる。
