KGaA, Weinheim Producing zeolite films with controlled preferred orientation on an industrial scale is a long-standing challenge. Herein we report on a scalable approach to the direct wet deposition of zeolite thin films and membranes while maintaining a high degree of control over the preferred crystal orientation. As a proof of concept, thin films comprising aluminophosphate zeolite AEI were cast on silicon wafer or porous alumina substrates. Electrical properties and separation performance of the zeolite thin films/membranes were engineered through controlling degree of preferred crystal orientation.enGIWAXS | polycrystal orientation | thin films | wet deposition | zeolitesScalable Wet Deposition of Zeolite AEI with a High Degree of Preferred Crystal Orientationjournal article10.1002/anie.201807430300767452-s2.0-85052805993WOS:000445445700050https://api.elsevier.com/content/abstract/scopus_id/85052805993
