Abstract
A phosphonate-based metal-organic framework membrane was constructed on a porous anodic alumina membrane (PAAM) substrate for H/CH separation for the first time. Owing to the ultra-micro pore windows, this membrane exhibited effective size exclusion for CH molecules but suitable permeance for H molecules, giving rise to an exceptional high H/CH separation selectivity.
摘要
首次在多孔阳极氧化铝膜（PAAM）基底上构建了一种基于膦酸盐的金属有机框架膜用于H/CH分离。由于其超微孔窗口，该膜对CH分子表现出有效的尺寸排阻作用，但对H分子具有合适的渗透率，从而产生了极高的H/CH分离选择性。
