Outline of Final Research Achievements

Activated carbon powders, zeolite powders and carbon nanohorns were added to organic gels synthesized from phenol and formaldehyde, and carbon cryogels containing particulates were prepared by unidirectional freezing, freeze drying and pyrolysis. The particulates were fabricated to honeycomb morphology, and porous properties of carbon cryogels were improved by mixing activated carbons or zeolites.
Next, alumina particulates were molded by unidirectional freezing of slurry including gelatin as a binder, and then alumina sintered bodies were obtained. High-strength alumina sintered bodies with honeycomb morphology and uniform pore distribution were successfully prepared by tuning preparation conditions. Platinum supported alumina sintered bodies could be also prepared without special reduction treatments.
