Zeolitic (molecular sieves) or mesoporous materials are the promising candidates for nanoscopically-engineered materials due to their well-defined pore structures, thermal stabilities and tailor-made synthetic abilities. Several zeolitic materials with the shape of nanorod or nanofiber have been synthesized. MFI (silicalite-1) monolayer can be coated tightly on TiO2 with the concept of 'nanoglue'. Nanoporous materials could be self-assembled by the function of a transition metal species as nanoglue under microwave irradiation. Nanocrystals shaped with rod or fiber show their own characteristics of catalysis, separation and sorption properties. Fibrous Ti-containing silicalite, which is stacked with several TS-1 nanocrystals having a hockey-puck shape, shows the increased photocatalytic activity of carbon dioxide with water. This TS-1 also has a character of preferential adsorption through longer chains. This fabrication causes more population on tetrahedrally coordinated Ti species as well as the more lengthened straight pores with higher hydrophobicity, which resulted in the improved catalysis and specific separation. Nanorod-shaped VSB-5 shows remarkable hydrogen adsorption capacity. With the help of nanoglue concept, thin films of porous materials can be prepared and are applied to separations. This work demonstrates that nanofabricated nanoporous materials with various morphologies by microwave irradiation may be applied for many potential uses.
