Mixed domain models for the distribution of aluminum in high silica zeolite SSZ-13

High resolution solid-state silicon-29 NMR has been used to determine the relative concentration of non-equivalent silicon atoms in SSZ-13. A mixed domain distribution model based on the use of hexagonal prisms has been found to be a viable method in understanding this distribution. Aluminum-27 MAS and MQMAS NMR allow the identification of multiple aluminum environments in zeolite SSZ-13.
