Direct synthesis of hierarchical zeolite from a natural layered material.
Hierarchical SAPO-34 zeolite with high crystallinity and excellent hydrothermal stability was directly synthesized in the nanoscale confined environment provided by the natural layered material kaolin.
متن کاملExpansion of the ADOR Strategy for the Synthesis of Zeolites: The Synthesis of IPC‐12 from Zeolite UOV
The assembly-disassembly-organization-reassembly (ADOR) process has been used to disassemble a parent zeolite with the UOV structure type and then reassemble the resulting layers into a novel structure, IPC-12. The structure of the material has previously been predicted computationally and confirmed in our experiments using X-ray diffraction and atomic resolution STEM-HAADF electron microscopy....
متن کاملOrganosilane with gemini-type structure as the mesoporogen for synthesis of hierarchical porous ZSM-5 zeolite
A new kind of organosilane (1,6-bis (diethyl(3-trimethoxysilylpropyl)ammonium) hexane bromide) with a geminitype structure was prepared and used as a mesoporogen for the synthesis of hierarchical porous ZSM-5 zeolite. There are two quaternary ammonium centers along with double hydrolysable -RSi(OMe)3 fragments in the organosilane, which results in a strong interaction between this mesoporogen a...
متن کاملOrganic-free synthesis of layer-like FAU-type zeolites.
The formation of layer-like FAU-type zeolites was facilitated in the absence of any organic template. Instead, the addition of simple inorganic salts turned out to be an effective and easy to handle alternative to organic additives to induce morphological and even structural changes during zeolite crystallisation.
متن کاملOrganotemplate-free synthesis of an open-framework magnesium aluminophosphate with proton conduction properties.
A new open-framework magnesium aluminophosphate MgAlP2O7(OH)(H2O)2 (denoted as JU102) has been hydrothermally synthesized by using an organotemplate-free synthetic route in the Al2O3-P2O5-MgO-H2O system. JU102 exhibits novel 4-connected zeolite-like topology with 8-ring channels. The existence of coordinated water and extensive H-bonds in the structure endows JU102 with unique proton conduction...
