Abstract
Anodic alumina(Anodisc)를 지지체로 사용하여 MFI 제올라이트 박막을 제조하였다. 먼저 화학결합을 이용하여 지지체에다 silicalite-1 종자 결정(c-축 길이 1.2 μm)을 결합시켰고, 제올라이트 단층막으로 덮인 지지체 위에 이차성장 수열합성법을 사용하여 결정들이 a-축과 b-축으로만 배향된 제올라이트 박막을 형성하였다. 제조된 박막은 주사형 전자현미경으로 관찰하였고, X-ray 회절로 분석하였다.
MFI zeolite membranes were prepared on anodic alumina (Anodisc) as support. First, silicalite-1_x000D_
(≒1.2 μm) seed crystals were attached to the surface of the support via chemical bonding, and the a- and b-axis oriented zeolite membranes could be synthesized on the support coated with the monolayer of the seed crystals by secondary growth hydrothermal synthesis. The zeolite membranes prepared were characterized using scanning electron microscope and analyzed by X-ray diffraction.
