Understanding the Mechanism of Nontraditional Zeolite Synthesis Using <i>In Situ</i> Nuclear Magnetic Resonance Spectroscopy and X-ray Diffraction.

ABSTRACT: In situ solid-state nuclear magnetic resonance (NMR) spectroscopy and in situ powder X-ray diffraction (PXRD) experiments are used to develop mechanistic insights into the disassembly and organization steps of nontraditional zeolite synthesis using the ADOR (Assembly, Disassembly, Organization, Reassembly) process. The work focuses on the reaction of the germanosilicate zeolite UTL to form two ADOR intermediates: IPC-1P on reaction with water and IPC-2P on reaction with aqueous HCl. The changes in the local structure on reaction with water can be modeled as one overall disassembly process, but the long-range changes, as measured by changes in interlayer spacing determined by XRD, indicate multiple stages of the reaction as the layer structure develops. For the reaction with a
