摘要/Abstract

摘要： 采用功能化无机粒子“二合一”修饰的方法, 通过将3-氨丙基三乙氧基硅烷(APTES)功能化的α-Al₂O₃粒子负载在大孔的管状载体上制备了类沸石咪唑框架(ZIF-7)膜, 考察了APTES的用量对ZIF-7膜制备的影响。结果表明, 嫁接有APTES的α-Al₂O₃粒子负载在载体上, 有效降低了载体表面孔尺寸并增加了载体表面异相成核的位点, 促进了膜的生长, 在APTES与α-Al₂O₃粒子的摩尔比为1:3时, 能够制得致密连续较薄的ZIF-7膜,?膜厚度大约为2~3 μm, H2的渗透通量为 4.70×10^-7 mol/(m²·s·Pa), H₂/CO₂、H₂/N₂的理想分离因数分别为5.87、4.59, 均大于努森扩散系数。

关键词: 功能化无机粒子, ZIF-7膜, 气体分离

Abstract: A ‘‘two-in-one’’ approach, namely, through deposition of APTES-functionalized Al₂O₃ particles onto a coarse macroporous support, was applied to synthesize zeolitic imidazolate tramework-7 (ZIF-7) membranes. The effect of molar ratio of APTES and Al₂O₃ particles on the formation of ZIF-7 membranes were investigated in detail.
When nAPTES:nAl₂O₃=1:3, the obtained continuous and thin ZIF-7 membrane with thickness ranging from 2 to 3 μm exhibited H₂ permeance at 4.70×10^-7 mol/(m²·s·Pa). Its ideal molecular sieving selectivity of H₂/CO₂ and H₂/N₂ was at 5.87 and 4.59, respectively.

Key words: functional inorganic particles, ZIF-7 membrane, gas separation
