Preparation method of randomly assembled mesostructure constructed with hierarchically mesoporous and microporous MFI zeolite nanosheets of single-unit-cell thickness, using water glass as the silica source

摘要

PURPOSE: A method for manufacturing MFI zeolite molecular material is provided to shorten time required for completing synthesis and save cost required for manufacturing processes by adjusting synthetic environment. CONSTITUTION: A method for manufacturing MFI zeolite molecular material includes the following: organic surfactant is polymerized with an inorganic precursor containing water glass to form organic-inorganic complex gel; the inorganic gel region of the organic-inorganic gel is converted into zeolite through a crystallization process; and the zeolite is separated from the mixture. The organic surfactant includes two or more ammonium functional groups, one ammonium functional group and one amine functional group. The organic surfactant is represented by chemical formula 1 or 2.
