Outline of Final Research Achievements

Following organic　nano-to-micro structures were prepared and converted to carbon materials. Cyclodextrin microcubes that were pre-treated with iodine or cross-linkers could be converted to microporous carbon materials with retaining the cubic shape by heating up to 900 at 1 degree/min under Ar. Micro-to-nano particles of hydroxyethylcellulose-lignin composites were prepared from the reverse micell alkaline solution by a precipitation method. The composite particles were converted to microporous carbons with meso-to macropores that had large surface area. Nano-to-micro spheres of hydrothermal carbons were prepared from cellulose dispersed in water at 220 degree in an autoclave. The hydrothermal carbon particles were activated by phosphoric acid at 450 degree and successively carbonized at 900 degree. After the treatments, hierarchical porous carbon materials with microporous surface and meso-to-macroporous spaces between the particles could be obtained.
