Zeolite Thin Films and Membranes: From Fundamental to Applications

Abstract

Zeolite fi lms and membranes have extensively been investigated since 1992. Many new preparation methods and concepts have been developed, such as microwave synthesis, intergrowth supporting substances, covalent linker synthesis, inner-side synthesis, fl uoride-mediated synthesis, variable-temperature synthesis, masking technique, counter-diffusion secondary growth, and pore-plugging synthesis. The remarkable progress made in the preparation has stimulated many application researches of zeolite fi lms and membranes, such as dehydration of various organic solvents, organics extraction from organic/water mixtures, separation of organic mixtures, gas separation, oil-water separation, desalination of seawater, membrane reactors, membrane microreactors, low-k materials, corrosion-resistant materials, sensors, fuel cells, and batteries. The recent progress in preparation and applications of zeolite membranes from 2000 has been summarized in this chapter.

A Review of Biorefinery Separations for Bioproduct Production via Thermocatalytic Processing

“…Wang & Yan (125) and Wang et al (126) provide a review of the pervaporation performances of zeolite membranes for dehydration of various organic solvents. Caro et al (127), Gascon et al (128), and Rangnekar et al (129) highlight the advancements in industrial implementation.…”

Selective catalytic reduction of NO over hierarchical Cu ZSM-5 coated on an alumina foam support

“…3 Monolayer films of ZSM-5 synthesized on stainless steel and aluminium alloy by in situ hydrothermal crystallization were studied by Wang and Yan. 4 Jia Ding et al performed NH 3 SCR on microfibrous-structured Cu ZSM-5/Alfiber catalysts, which show high activity due to enhanced mass transfer. 5 Yashnik et al studied the effect of different states of copper, isolated Cu 2+ , Cu 2+ with extra lattice oxygen and CuO in Cu ZSM-5 on the NH 3 SCR reaction.…”

Methods and synthesis parameters affecting the formation of FAU type zeolite membrane and its separation performance: a review

“…Zeolite membranes offer several advantages over organic membrane and other types of inorganic membrane due to their attractive characteristics such as adaptability to harsh environment, long-term stability at high temperature and pressure, molecular sieving, catalytic, and selective sorption properties [2]. Due to these properties, zeolite membranes can be used for various applications including gas separation, pervaporation, solvent dehydration, membrane reactors, coating materials, catalytic microreactors, gas sensor, and fuel cells [3][4][5][6][7][8]. Zeolite membrane was firstly prepared by Suzuki in 1987, where a continuous zeolite layer was prepared on a porous support [9].…”
