| Outline of Final Research Achievements |
In this research, we developed microporous boron nitride (p-BN). BN is equielectronic with typical graphitic carbon. We succeeded in preparing p-BN composed of both micropores and mesopores. The resistance to thermal oxidation under the atmosphere was revealed to be remarkably superior to that of carbon materials. In addition, a lot of results obviously indicate the p-BN has a stronger interaction with nitrogen molecules than carbon materials due to its specific surface nature. The current study opened up the possibility of using it as a new adsorption material and catalyst carrier.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で対象とした細孔性窒化ホウ素は、炭素材料の一つである活性炭と構造的に非常に類似しているにも関わらず、炭素材料よりも大気中での熱酸化耐性に優れ、また、窒素ガスに対する親和性が高いなど、細孔性窒化ホウ素の新たな用途開拓の基礎となる研究成果を見出した。原子レベルの不均一表面が発現するユニークな特徴である点は学術的に興味深い。今後は、幾つかの課題を解決しつつ、高耐久性を誇る吸着材料や触媒担体としての応用利用に向けた基礎データの蓄積と新たな材料創製手法の開発を中心に研究を展開する。
