Outline of Final Research Achievements |
A new preparation method of porous hard carbon was proposed that applies two thermal treatments (hydrothermal treatment and carbonization) to organic raw materials containing different metal species and precisely simultaneous controls morphologies of both nano-space and bulk of the carbons. The hydrothermal treatment provided various porous spherical carbons with the structural advantages of the raw materials. The potential for new manufacturing that scopes to carbon neutrality was also demonstrated by applying this method to the modification of biomass resources and the materialization of industrial waste.

Academic Significance and Societal Importance of the Research Achievements |
本成果は,水熱処理の利点を最大限生かしながらナノ空間とバルク形態の一体制御に取り組んだものであり,エネルギー貯蔵用の基盤材料の低コスト化および高品質化を図ることができる。安価なセルロース系原料の他,産業廃棄物を炭素源することで,その含有炭素をほぼ固定炭素(炭)として取り出し,同時に多孔性を付与することができるため,材料用途の分野が広がるだけでなく,カーボンニュートラルに貢献できる合成法と言える。
