Abstract

Discrete spherical colloidal TPA-silicalite-1 with the gel composition 1.0TPAOH:3.0SiO₂:100H₂O:xPromoter (Promoter= H ₂SO₄, HCl, HNO₃ and NH₄OH, x=0-0.5) has been synthesized at 100°C. The spherical compounds modified as functions of acidic species and added promoter amount were fully investigated using PXRD, SEM, Light scattering, Zeta potential and ²⁹Si solid NMR. The mean sizes of H₂SO₄ -induced TPA-silicalite-1 were ranged from 200 to 500nm and agreed with the results of the light scattering. The spherical morphology of the TPA-silicalite-1 was compared with a typical silicalite-1 with multiple twins and hillock. These facts suggest acidic promoter addition in TPA-silicalite enhanced the interaction of TPA⁺ and the silica source, leading the effect of nucleation and crystallization, and led the preferred orientation of crystal growth due to regulate the shape of TPA-silicalite-1.
