Abstract

Well-intergrown ZIF-8 membranes are prepared directly from zinc hydroxide nanostrands without any modification of the substrate in ethanol–water at room temperature in a short time and exhibit high molecular sieving performance for gas separation after secondary growth. This strategy exhibits excellent reproducibility and versatility and is suitable for large-scale production.
