PBI mixed matrix hollow fiber membrane: Influence of ZIF-8 filler over H₂/CO₂ separation performance at high temperature and pressure

High performance and commercially attractive mixed-matrix membranes were developed for H₂/CO₂ separation via a scalable hollow fiber spinning process. Thin (~300 nm) and defect-free selective layers were successfully created with a uniform distribution of the nanosized (~60 nm) zeolitic-imidazole framework (ZIF-8) filler...

Insights into micro-structure and separation mechanism of benzimidazole-linked polymer membrane for H₂/CO₂ separation

Separation of hydrogen from carbon dioxide for sustainable H₂ production and CO₂ capture still faces great challenges due to the smaller size of H₂ and higher condensability of CO₂. Herein, a high-performance benzimidazole-linked polymer (BILP) membrane for hydrogen separation was directly prepared...
