Accelerated synthesis of ferrierite nanoneedles via the ETL seed-assisted approach for catalytic ethanol dehydration
The rational design of zeolite nanostructures at the molecular level significantly impacts their properties and catalytic performances in various reactions, especially alcohols-to-hydrocarbons. However, most synthesis methods involve complex and time-consuming processes. To address these challenges, developing a new synthesis method to obtain hierarchical zeolites via an integrated one-step and rapid synthesis approach could be a promising research contribution. Herein, we report that the crystallization of hierarchical FER zeolite can be effectively accelerated via the ETL zeolite seed-assisted approach, resulting in a decrease of synthesis time. This behavior can be explained by the fact that both FER and ETL zeolites contain similar main building units, namely mor, which can assist the formation of FER when using ETL as seeds. As a result, the FER framework can be directly constructed from the building units of the ETL seed. In addition, the nanorod-like structure of ETL seeds can affect the target FER morphology, eventually forming hierarchical nanoneedle features. The catalytic activities of the synthesized hierarchical FER with a nanoneedle shape were also systematically investigated in ethanol dehydration, demonstrating the advantages of the designed materials compared to the conventional one.
期刊介绍:
Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous (pore size up to 2 nm) or mesoporous (pore size 2 to 50 nm). The porosity should have a specific impact on the material properties or application. Typical examples are zeolites and zeolite-like materials, pillared materials, clathrasils and clathrates, carbon molecular sieves, ordered mesoporous materials, organic/inorganic porous hybrid materials, or porous metal oxides. Both natural and synthetic porous materials are within the scope of the journal.
Topics which are particularly of interest include:
All aspects of natural microporous and mesoporous solids
The synthesis of crystalline or amorphous porous materials
The physico-chemical characterization of microporous and mesoporous solids, especially spectroscopic and microscopic
The modification of microporous and mesoporous solids, for example by ion exchange or solid-state reactions
All topics related to diffusion of mobile species in the pores of microporous and mesoporous materials
Adsorption (and other separation techniques) using microporous or mesoporous adsorbents
Catalysis by microporous and mesoporous materials
Host/guest interactions
Theoretical chemistry and modelling of host/guest interactions
All topics related to the application of microporous and mesoporous materials in industrial catalysis, separation technology, environmental protection, electrochemistry, membranes, sensors, optical devices, etc.
