Recently, ZIF-78 MOF has gained attention as a promising metal-organic framework (MOF) material for the fabrication of mixed matrix membranes (MMMs) for gas separation applications. In order to create Polyamide (PA) mixed-matrix membranes (MMMs) for CO2/N2 separation, ZIF-78 MOF was used as a filler in this work to get around the performance trade-off of traditional polymeric membranes. A high aspect ratio and a low one ZIF-78 particles are created and added to a matrix of polyamide (PA). SEM and XRD were used to evaluate the microstructures and physico-chemical characteristics of the ZIF-78 fillers and ZIF-78/PA MMMs. Through the use of a solution-diffusion model and permeation measurements at different input pressures, the CO2/N2 transport characteristics through the MMMs were assessed. Due to the ZIF-78 filler's molecular sieving action, the results demonstrated that adding ZIF-78 to PA improved both CO2 permeability and CO2/N2 selectivity. The MMM with the ideal ZIF-78 loading of 15 wt% demonstrated CO2/N2 of 25 and CO2 permeability of 211 barrer, both of which exceeded the 2008 Robeson upper-bound, indicating that a ZIF-78-based membrane would be a viable option for purifying natural gas.
