Organosilane 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 کاملA hierarchical Fe/ZSM-5 zeolite with superior catalytic performance for benzene hydroxylation to phenolw
Phenol is an important industrial intermediate for the production of various chemicals such as bisphenol A, phenolic resins, caprolactam, alkylphenols and adipic acid. The cumene hydroperoxide process is the currently used industrial method to produce phenol. Its environmentally stressing aspects have spurred research to replace this process with more benign approaches such as the direct oxidat...
متن کاملA hierarchical Fe/ZSM-5 zeolite with superior catalytic performance for benzene hydroxylation to phenol.
We report the one-step synthesis of a highly active hierarchical Fe/ZSM-5 zeolite catalyst with a strongly improved lifetime in the selective hydroxylation of benzene to phenol with nitrous oxide; compared to the best Fe/ZSM-5 catalyst, the turnover number after 24 h on stream is almost four times higher.
متن کاملHierarchical Macro-meso-microporous ZSM-5 Zeolite Hollow Fibers With Highly Efficient Catalytic Cracking Capability
Zeolite fibers have attracted growing interest for a range of new applications because of their structural particularity while maintaining the intrinsic performances of the building blocks of zeolites. The fabrication of uniform zeolite fibers with tunable hierarchical porosity and further exploration of their catalytic potential are of great importance. Here, we present a versatile and facile ...
متن کاملHigh-pressure cation-exchange treatment of a ZSM-5 zeolite
ZSM-5 zeolite is an aluminosilicate that usually has a high silica-to-alumina ratio. It contains two sets of nanopores. One set of nanopores is straight, with the cross-sectional size of 5.3 5.6 Å; the other set is Sshaped, with the cross-sectional size of 5.2 5.5 Å. An A1 atom at the center of an AlO4 tetrahedron connects to adjacent SiO4 tetrahedron by sharing an O atom and thus generates a n...
