ZIF-8 modified with 2-undecylimidazolate as filler for mixed matrix membranes for CO₂ separation

Abstract

A novel modification of zeolitic imidazolate framework-8 (ZIF-8) with 2-undecylimidazolate (umIm) was explored to enhance its hydrophobic character and improve its compatibility with polymer of intrinsic microporosity PIM-1 when incorporated...

Challenges and recent advances in MOF-based gas separation membranes

“…The performance of polymer membranes is currently limited by trade-off effects, which makes it difficult to realize high selectivity and high permeability. 12,13 On the other hand, inorganic membranes are hindered from being used in large-scale applications by their high price. Therefore, the preparation of efficient, stable, and inexpensive gas separation membranes is the goal pursued by membrane-based gas separation.…”
