N2 - Mixed matrix membranes (MMMs) could be a solution to combine the advantage of organic polymer and inorganic membrane for CO2 gas separation. In this research, MMMs based on poly-ether sulfone (PES) with various amounts addition of Metal–Organic Framework based on magnesium(II) and benzene 1,3,5- tricarboxylate [Mg3(BTC)2], as filler, have been prepared via phase inversion method. According to FTIR spectroscopy, the obtained MMMs show no chemical interaction between [Mg3(BTC)2] and PES. Post-synthesis sonication on [Mg3(BTC)2] resulted in 5 times smaller particle size and increased the surface area up to 8 times. The loading of [Mg3(BTC)2] slightly increases the thermal stability of the PES membrane up to 20 °C according to thermogravimetric analysis (TGA). High [Mg3(BTC)2] loading of 30 and 40 wt% resulting in particle agglomeration as depicted in scanning electron microscope (SEM) images. The value of CO2 permeability increased almost five times after loading of 20 wt% [Mg3(BTC)2] into PES, while the selectivity of CO2/N2 and CO2/O2 separation increased up to 200 and 150%, respectively.
