The separation of C2H4 and C2H6 is a critical yet energy-intensive operation in the petrochemical industry. Gas membranes offer energy-efficient alternatives, but their effectiveness hindered by similar physical properties C2H6. Here, metallic nanocomposite membrane (MNM) comprising ultra-small Ag nanoparticles embedded an amidoxime-modified polymer intrinsic microporosity (AOPIM-1) reported for highly efficient C2H4/C2H6 separation. microporous structure AOPIM-1, combined with anchoring groups (amidoxime groups) inside microcavities, enables size-controlled growth ‒≈3 nm diameter, which maximizes contact ethylene molecules. amidoxime as electron acceptors effectively enrich positive charge on surface nanoparticles. activated form reversible complexes molecules endowing them preferential affinity over ethane. resulting demonstrates ≈10-fold increase permeability, reaching 322.1 barrer, ≈3-fold selectivity, 8.8. comprehensive performance superior all mixed matrix so far.

Abstract Ultrathin continuous metal–organic framework (MOF) membranes have the potential to achieve high gas permeance and selectivity simultaneously for otherwise difficult separations, but with few exceptions zeolitic‐imidazolate frameworks (ZIF) membranes, current methods cannot conveniently realize practical large‐area fabrication. Here, we propose a ligand back diffusion‐assisted bipolymer‐directed metal ion distribution strategy preparing ultrathin MOF on flexible polymeric support layers. The bipolymer directs ions form cross‐linked two‐dimensional (2D) network uniform of Ligand diffusion controls feed molecules available nuclei formation, resulting in growth membranes. We report fabrication three representative defect‐free areas larger than 2,400 cm 2 selective layers (50–130 nm), including ZIFs carboxylate‐linker MOFs.

Abstract Metal–organic framework (MOF) membranes are widely used in gas separation processes. However, the effect of solvents on formation large‐area MOF membranes, which directly influences performance, has rarely been investigated. In this study, three (methanol, ethanol, and water) were selected to systematically investigate their effects zeolite imidazolium frameworks (ZIF) membrane via experimental validation simulations. The results indicated that solvent selection influenced crystallization rate, crystal size, ZIF‐8 ability. Particularly, when water was as a solvent, slow nucleation crystals observed, resulting more complete structure thinner membrane. Therefore, exhibited permeance 10,000 permeation unit enhanced CO 2 /N selectivity. Furthermore, with surface area 2400 cm spiral‐wound modules developed, paving way for large‐scale industrial production.

Porous organic frameworks (POFs) are novel porous materials that have attracted much attention due to their extraordinary properties, such as high specific surface area, tunable pore size, stability and ease of functionalisation. However, conventional synthesised POFs mostly large-sized particles or insoluble powders, which difficult recycle low mass transfer efficiencies, limiting the development cutting-edge applications. Therefore, processing POF into membrane structures is great significance. In recent years, interface engineering strategies proved be efficient methods for formation membranes. this perspective, advances in use interfaces prepare membranes reviewed.
