Abstract

Tetrapropylammonium (TPA)‐containing precursors are the building blocks in the crystallization of silica. In the first steps slab‐shaped silicalite nanoparticles are formed by ordered combination of the precursors (see picture). These nanoslabs have MFI‐type zeolite framework topology and play a key role in TPA‐ion‐mediated zeolite crystallization from monomeric and polymeric silica sources.
