Preparation of partially oriented zeolite MCM-22 membranes via pulsed laser deposition

Fabrication of Oriented Silver-Functionalized RPM3 Films for the Selective Detection of Olefins

“…Another method known as pulsed laser deposition (PLD) is an interesting seeding approach because it directly “anchors” the porous material to the substrate of choice. The PLD method has been used to prepare oriented thin films of molecular sieves including UTD-1, AlPO 4 -5, FeAPO-5, MCM-41, MCM-22, NaX, , UTD-12, ZSM-5, and ZSM-48 . PLD produces high energy atoms, ions, and molecules that are deposited on a substrate, which are then hydrothermally treated to form a crystalline film.…”

Long-term flue gas exposure effects of silica membranes on porous steel substrate

“…Initial work in this area included coating zeolite membranes onto porous steel substrates using crystallization [6], secondary seeded growth [7] and pulsed laser techniques [8]. The best of these membranes achieved a reasonable H 2 /CO 2 selectivity of 8.25 at a hydrogen permeance of 1.36 × 10 −7 mol m −2 s −1 Pa −1 [9].…”

Hydrovapothermal conversion of tetraethoxysilane vapor to polycrystalline zeolite layer by in situ gelationElectronic supplementary information (ESI) available: SEM images and seeding method. See http://www.rsc.org/suppdata/cc/b4/b400207p/

“…Fabrication of membrane is pivotal for zeolite-membrane-based technology and continues to draw considerable attention in research and development due to its indisputable control over the microstructure and sorption properties of the membrane. [1][2][3][4][5][6][7][8][9][10][11][12] The lack of simple, reproducible and economic method producing high performance membrane in large scale poses the hardest obstacle to the industrial realization of many desirable processes implementing a robust zeolite-membrane-based technology. Commercialization of zeolite membrane has been achieved only recently for the dehydration of alcohol.…”
