Vacuum-Assisted Confined Growth of MOF@COF Composite Membranes with Enhanced Hydrogen Permselectivity.
Angew Chem Int Ed Engl
December 2024
Article Synopsis
- Covalent organic frameworks (COFs) have potential for creating high-quality separation membranes but face challenges in gas separation due to larger pore sizes.
- The study introduces a novel method by embedding the metal-organic framework (MOF) ZIF-8 within TB-COF to enhance gas separation properties.
- The resulting ZIF-8@TB-COF membrane achieves significantly increased hydrogen selectivity for separating gas mixtures compared to traditional COF membranes, demonstrating the effectiveness of this new synthesis approach.
Ultrathin Two-Dimensional Porous Fullerene Membranes for Ultimate Organic Solvent Separation.
Angew Chem Int Ed Engl
April 2024
Two-dimensional (2D) materials with high chemical stability have attracted intensive interest in membrane design for the separation of organic solvents. As a novel 2D material, polymeric fullerenes (C) with distinctive properties are very promising for the development of innovative membranes. In this work, we report the construction of a 2D (C) nanosheet membrane for organic solvent separation.

In this work, a new farfalle-shaped ZIF with an ordered hierarchical structure (named ZIF-F) was easily built with zinc acetate and 2-methylimidazole (MeIm) in an aqueous system at room temperature. The synthesis mechanism of ZIF-F is a dual-induction interaction of a solvent and zinc source based on the synthesis protocol of ZIF-8.
