Outline of Final Research Achievements

Titania cryogel fibers and titania-silica cryogel fibers with various titania contents were synthesized by using unidirectional freezing. Since the fibers prepared had higher BET surface areas and larger mesopore volumes than those of a commercial photocatalyst, P-25, they showed higher photocatalytic activity towards the decomposition of large organic molecules than P-25. Hollow fibers of MFI type zeolite with high crystallinity were also synthesized by unidirectional freezing and steam-assisted crystallization. Their degree of crystallinity and crystal size could be independently controlled by the concentration of structure-directed agency, the crystallization temperature and the crystallization time.
Next, fibrous sintered bodies of alumina were synthesized by using organic gels prepared from phenol and formaldehyde as a binder. Their morphology and porous structure could be controlled by the conditions of unidirectional freezing and the application of ultrasonic wave to gels.
