Sandwich-type zeolite intergrowths with MFI and the novel extralarge pore IDM-1 as ordered end-members 2021 Access copy available to the general public Unrestricted Stacking faults are two-dimensional planar defects frequently arising in zeolites, modifying their properties and potentially affecting their performance in catalysis and separation applications. In classical zeolite intergrowths, a topologically unique zeolite layer may often pile up after some spatial transformation (lateral translation, rotation, and/or reflection) that may occur in different amounts or directions with about similar probabilities, leading to a difficult to control disorder. Here, we present a new kind of zeolite intergrowth that requires an additional topologically distinct layer rather than a spatial transformation of a unique one. Stacking of the so-called pentasil layers produces the well-known medium pore zeolite MFI. Intercalation in strict alternation of a topologically distinct second layer sandwiched between pentasil layers expands the structure to produce the new extra-large pore IDM-1. Stacking disorder modulates the structural expansion along the stacking direction. The disordered materials have been studied by simulation of the X-ray diffraction patterns using the program DIFFaX and by Cs-corrected high-resolution electron microscopy. We show that disorder does not occur at random but in extended domains and can be controlled all the way from MFI to IDM-1 by just varying the concentration of the synthesis mixture. info:eu-repo/grantAgreement/ES/DGA/E13-20R info:eu-repo/grantAgreement/ES/MCIU-FEDER/RTI2018-101599-B-C22 info:eu-repo/grantAgreement/ES/MCIU/PID2019- 105479RB-I00 info:eu-repo/grantAgreement/ES/MCIU/RYC-2018-024561-I info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/MAT2015-71117-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 10.508 2021 MATERIALS SCIENCE, MULTIDISCIPLINARY 48 / 345 = 0.139 2021 Q1 T1 CHEMISTRY, PHYSICAL 31 / 165 = 0.188 2021 Q1 T1 2.93 2021 Chemistry (miscellaneous) 2021 Q1 Chemical Engineering (miscellaneous) 2021 Q1 15.9 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Li, Jain.
