第一个连续和良好共生的M0 F-5膜，由SEM成像和X射线衍射（XRD）证明。采用原位溶剂热合成法在多孔α-氧化铝基体上成功制备了纳米TiO 2。对取自用于膜合成的相同母液的晶体的BET测量得到2259 m2/g的朗缪尔表面积和以1.56 nm为中心的窄孔径分布。对H_2、CH_4、N_2、CO_2和SF_6等简单气体的渗透数据表明，简单气体在MOF-5膜中的扩散遵循努森扩散行为。(C)2008年爱思唯尔公司All rights reserved.
The first continuous and well-intergrown MOF-5 membrane, evidenced from SEM imaging and X-ray diffraction (XRD). was successfully prepared on porous alpha-alumina substrate by in situ solvothermal synthesis. The BET measurements on crystals taken from the same mother liquor that was used for membrane synthesis yield a Langmuir surface area of 2259 m(2)/g and a narrow pore size distribution centered at 1.56 nm. The permeation data for simple gases of H-2, CH4, N-2, CO2 and SF6 show that the diffusion of simple gases through a MOF-5 membrane follows the Knudsen diffusion behavior. (C) 2008 Elsevier Inc.
