Controllable surfactant-directed zeolitic-imidazolate-8 growth on swollen 2D zeolites

To meet society’s need for more and specialized materials, this work focuses on the preparation of porous metal–organic framework (MOF)–zeolite hybrid materials based two 2D zeolites, namely, IPC-1P (Institute Physical Chemistry - 1 Precursor) ZIF-8 (Zeolitic Imidazolate Framework-8). Using previously well-established assembly–disassembly–organization–reassembly method, zeolite was (i) synthesized, (ii) hydrolyzed to a layered zeolite, (iii) interlayer distance increased using swelling agent cetyltrimethylammonium chloride, (iv) nanocrystals were grown stepwise surface but predominantly at edges crystallites where openings region are located. This selective MOF growth attachment facilitated by combination intercalation metal ions between layers. The influence solvent number additional steps systematically investigated, synthesis protocol successfully adapted further two-dimensional silicate RUB-18 (Ruhr-Universität Bochum 18). paves way toward controlled MOF–zeolite which might provide interesting properties future applications.
