(58ah) Highly Selective MOF Based MMM Integrated with CNTs for CO2 Separation Purpose

Carbon Nanotubes (CNTs) were synergistically integrated to polysulfone (PSF) to develop a highly selective mixed-matrix membranes (MMMs) for CO₂ separation purpose in a presence of a metal organic framework (MOFs). This study aims to integrate CNTs with metal organic frameworks into a MMM to separate CO₂ efficiently. The results show that filled MMMs with about 5 wt % CNTs showed an optimum separation performance by providing a CO₂/N₂ selectivity of about 50. Increasing CNTs additives resulted in in lowering the selectivity.
