Organic-free synthesis of layer-like FAU-type zeolites.
نویسندگان
چکیده
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.

On the performance of FAU and MFI zeolites for the adsorptive removal of a series of volatile organic compounds from air using molecular simulation.
Volatile organic compound (VOC) emissions can cause serious risk to human health and the environment. In this work, we used Monte Carlo simulations to assess the performance of industrially important zeolites for the adsorption-based removal of a number of common air pollutants, particularly small saturated and unsaturated hydrocarbons: propane, butane, propene, and 1-butene. We focused on the ...
متن کاملEncapsulation of metal clusters within MFI via interzeolite transformations and direct hydrothermal syntheses and catalytic consequences of their confinement.
The encapsulation of metal clusters (Pt, Ru, Rh) within MFI was achieved by exchanging cationic metal precursors into a parent zeolite (BEA, FAU), reducing them with H2 to form metal clusters, and transforming these zeolites into daughter structures of higher framework density (MFI) under hydrothermal conditions. These transformations required MFI seeds or organic templates for FAU parent zeoli...
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 (...
متن کاملSynthesis of nanocrystalline zeolite NaY by hydrothermal method and investigation of its structure and morphology
Zeolite FAU type-Y is one of the most studied framework of all zeolites, and has been used as catalysts for number of reactions in the refinery and petrochemical industry. In this research, nanocrystalline zeolite Y was synthesized by hydrothermal method. The crystal size of zeolite Y is influenced by temperature, aging time, alkalinity, and water content. The synthesized zeolite NaY is identif...
متن کاملNanocrystalline Zeolite Y: Synthesis and Characterization
Nanocrystalline zeolite has received significant attention in the catalysis community. Zeolites with a crystal size smaller than 100 nm are the potential replacement for existing zeolite catalysts due to its unique features with added advantages. Zeolite FAU type Y is one of the most studied framework of all zeolites, and has been used as catalysts for number of reactions in the refinery and pe...
