Synthesis of ZIF‐94 from Recycled Mother Liquors: Study of the Influence of Its Loading on Postcombustion CO ₂ Capture with Pebax Based Mixed Matrix Membranes

Global energy demand is met in large part, by burning of fossil fuels, which causing global warming. Mixed matrix membranes (MMMs) with metal organic frameworks (MOFs) as fillers are an interesting alternative for capturing post combustion CO2 would make the sector sustainable. This research focused on synthesis MOF ZIF-94 from recycling its mother liquors and incorporation synthesized into a Pebax MH 1657 MMM fabrication. The pH temperature modified monitored this results various nanoparticle diameters (average particle size range 41 ± 8–180 73 nm). Incorporation significantly improves performance bare membrane. maximum CO2/N2 selectivity permeability obtained 10 wt% loading 9 (polymer concentration 70/30 (v/v) ethanol/water solution) being 36 7 (71% increment compared to membrane) 137 31 Barrer (80% improvement), respectively.
