The molecular sieving property of a continuous b-oriented pure-silica-zeolite (PSZ) MFI monocrystal film was demonstrated in a zeolite-modified electrode (ZME) configuration using redox molecules of different sizes. Ru(NH3)63+ (diameter approximately 5.5 A) was able to traverse the film, while Co(phen)32+ (diameter approximately 13.0 A) was completely excluded. This film has excellent adhesion to the electrode and is stable in strong acidic conditions.
在使用不同大小氧化还原分子的沸石修饰电极（ZME）配置中，证明了连续b取向纯硅沸石（PSZ）MFI单晶膜的分子筛特性。六氨合钌（III）离子（Ru(NH3)63+，直径约5.5埃）能够穿过该膜，而三联吡啶钴（II）离子（Co(phen)32+，直径约13.0埃）则被完全排除。该膜与电极具有优异的附着力，并且在强酸性条件下稳定。
