| Outline of Final Research Achievements |
The aim of this study is to develop a wood-based carbon material contributing to the solution of global warming problem by adsorbing and storing CO2 under atmospheric pressure. Activated carbon was made by changing the amount of Fe ion, mixing ratio of CNF, phenolic resin and activators in order to obtain the basic data for that purpose. The micropore structures were analyzed with CO2 adsorption measurement and transmission electron microscopy (TEM). An optimum condition was found for the amount of activators. Image analysis of TEM images and gas adsorption measurements revealed that it is important to secure the migration path to reach ultramicropores in the activated carbon in order to adsorb CO2 efficiently.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、炭素の空隙構造を制御することによりなぜCO2吸収能が上がるのかを解明する点で、学術的意義が高い。従来品と比較して圧倒的低コストで製造可能なCO2吸着材を開発することが、地球温暖化問題を解決する糸口になるからである。本研究によって得られる基礎的データは、科学技術イノベーションに寄与し、地球温暖化対策で利用されそこから卓越した成果が期待される。IPCC京都総会で土壌へのバイオ炭投入量が炭素貯留量へ貢献することとなり世界のCO2排出量削減につながる点で、本研究の社会的意義は極めて高いといえる。
