Seed-directed synthesis of zeolites with enhanced performance in the absence of organic templates.
نویسندگان
چکیده
We demonstrate here a seed-directed synthesis (SDS) of Beta, Levyne, and Heulandite zeolites in the absence of organotemplates, where the seeds drive crystallization of the zeolites. Compared with conventional Beta synthesized in the presence of organic templates, Beta-SDS exhibits large textural parameters, stable Al species, and unprecedentedly high density of active sites, resulting in superior catalytic activity and selectivity for valuable products in catalysis.

The Role of Ethanol, Methyltriphenylphosphonium Bromide and Cetyltrimethylammonium Bromide as Directing Agents in Hydrothermal Synthesis of Aluminosilicate Molecular Sieve (ZSM-5) and Its Morphologies
Zeolite ZSM-5 presents a great source of interest in catalysis because of its shape selective properties. The absence of a relationship between the template size and shape of the structure generated during the synthesis of zeolites is illustrated by the case of ZSM-5. In this study, we have investigated the role of ethanol, methyltriphenylphosphonium bromide (MTPBr) and cetyltrimethylammonium b...
متن کاملSynthesis of Zeolites via Interzeolite Transformations without Organic Structure-Directing Agents
We report synthetic protocols and guiding principles inspired by mechanistic considerations for the synthesis of crystalline microporous solids via interzeolite transformations that avoid direct intervention by organic structure-directing agents. These protocols are specifically implemented to synthesize highsilica MFI (ZSM-5), CHA (chabazite), STF (SSZ-35), and MTW (ZSM-12) zeolites from FAU (...

In this article, we have investigated the role of dimethylamine (DMA), tributylamine (TBA), Triethanoleamine (TEA), Trishydroxymethylamine (TRIZMA), and Hexamethyleneterraamine (HMTA), in the formation of zeolitic compounds. The experiments were carried out in acidic and basic media using Si/Al< 10 and Si/A1>10. The structure of the resulting synthetic zeolites were similar to Natro Davyne,...
متن کاملCatalytic properties of hierarchical mesoporous zeolites templated with a mixture of small organic ammonium salts and mesoscale cationic polymers.
Crystals of zeolites with intricate micropores have been widely used in industry as heterogeneous catalysts, in particular as solid acid catalysts in the fields of oil refining and petrochemistry. However, relatively small individual micropores in zeolites such as Beta, ZSM-5, and Y strongly influence mass transport to and from the active sites located within them, severely limiting the perform...

In the present research synthesis of zeolites, merlinoite minerals of natural clinoptiloite mineral in the presence of alkaline mediums, was investigated. The analyzed variants are a result of a concentration of Na+ and K+ ions, temperature and time. Phase transition of clinoptiloite was conducted in the presence of an 8 molar potash solution (KOH) and a 4 molar soda solution (NaOH). Results in...
