Abstract

Nanofabrication of nanoporous materials under microwave irradiation was successfully implemented by the adhesion of crystallites through the condensation of hydroxyl groups on surface via selective adsorption of microwave energy on Ti species as a nanoglue. This microwave technique gave births of both the uniform size of hockey puck shaped crystals and the stacking of these crystals into fiber or rod types in the synthesis of nanoporous materials such as MFI and AlPO-5 zeolites. The formation of these nanostacked MFI-type zeolite crystals having nanorod shape was ascribed to the presence of metal species, which selectively absorbed microwave irradiation. These fibrous MFI zeolites provide exciting and unique physicochemical properties, for example, low packing density, high stability of the fibrous morphology and the enhanced hydrophobicity. The fabricated Ti-MFI and AlPO-5 show preferential adsorption of p-xylene over o-xylene, which may suggest that a longish molecule can be adsorbed preferentially on the longish nanoporous materials.
