Synthesis and Rietveld Refinement of the Small-Pore Zeolite SSZ-16
Source abstract
Abstract
Rietveld refinement of synchrotron X-ray powder diffraction data of SSZ-16 shows that this zeolite is the aluminosilicate analogue of SAPO-56 (AFX). SSZ-16 contains a three-dimensional pore system with pores bounded by eight tetrahedral atoms, and is a member of the ABC... type of zeolites with an AABBCCBB... layer sequence. There is a very good fit between the size of the organic structure-directing agents used during the zeolite synthesis and the size of the large cages of SSZ-16.

22. The sample used for synchrotron XRD was treated as follows: the as-synthesized SSZ-16 was heated in air at 540 °C to remove the organic structure-directing agent occluded in the pores and was later dried at 350 °C under vacuum in a glass capillary which was then sealed. The synchrotron X-ray powder data were collected at the X7A beam line at the Synchrotron Light Source, Brookhaven National Laboratory, from 2 to 50° 2θ, using a wavelength λ = 1.1997 Å. The General Structure Analysis System (GSAS)20suite of programs was used for the Rietveld refinement of the synchrotron XRD data. No additional phases were detected in the XRD data, and all the peaks could be accounted for using the space groupP63/mmc.
