Zeolite fiber, film, and monolith were prepared by using nanosize titanium silicalite (TS-I) crystals. Films and fibers of TS-I zeolite were optically transparent, which might be important for advanced optozeolitic materials. A permeation result of gases on monolith indicates that the gas permeation is governed by the Knudsen mechanism. All types of Ts-1 zeolites manufactured in this work are observed to be MI;I structure with an orthorhombic symmetry. These results suggest that nanosize zeolites have potential to allow morphological design with applications for advanced functional materials.
