Abstract

Abstract: The synthesis of zeolites with special morphologies has attracted much attention, because the morphologies influence the efficiency of catalysis, applications as the hosts for micro-devices, and so on. Silicalite-1 with chain-like morphology (0.57—6.33 m) were synthesized successfully with poly(diallyldimethylammonium chloride) (PDDA) as an additive and was characterized by XRD and SEM. The PDDA as the additive in the synthesis system was the real key for the formation of the chain-like morphology of the products. The length and the diameter of the material can be tuned through adjusting the molar ratios of PDDA and TPAOH. The straight channels of materials are longer and their openings are much fewer than those of the traditional slicalite-1 crystals, because of the crystal stacking along the b axis.

Key words: Zeolite Silicalite-1 with chain-like morphology, Self-assembly, Poly(diallyldimethylammonium chloride)(PDDA)
