Fibrous zeolite has been prepared ftom titanium silicalite (TS-1) particles with less than 150 nm in diameter.The formation of fibrous titanium silicalite (FTS-1) zeolite was mainly affected by the particle size of TS-1 zeolite. FTS-1 is formed by both the capillary force and the dehydroxylation among the TS-1particles during the drying and evaporation process of the dispersed TS-1particles in aqueous solution.The average length and the aspect ratio (=length/diameter) of FTS-1 are 2.2 mm and 50~70, respectively.The obtained FTS-1 shows two dimensionally aligned surface.After calcination at 750°C,FTS-1 still exhibited charac-teristics of MFI-type Structure With orthorhombic symmetry.This method of FTS-1 for-mation may suggest a novel method for the preparation of various types of zeolite.Up to now,fibrous ZSM-5 (FZSM-5) was also obtained using nano sized ZSM-5 crystals.

Key words: Fibrous zeolite; Morphological change; FTS-1; FZSM-5; Nano sized zeolite; Capillary force
