“…Besides GO, its hybrids with porous fillers like zeolites, metal-organic frameworks (MOFs) are also dispersed in polymeric matrices for improving the membrane's robustness and separation ability. Karanikolos's group 102 integrated the inorganic ZIF-8/GO hybrid nanofillers into the organic PSF matrix via solution blending. The resulted mixed-matrix membranes (PSF+ZIF-8/GO) showed a sharp rise in CO 2 permeability (61% vs pristine PSF) and selectivity (87% vs pristine PSF) against CH 4 .…”

Graphene has been hailed as a revolutionary membrane material because of its many alluring features and the ease in their tunability. In specific to gas separation industry, the exceptional molecular transport, the possibility of fabricating membranes having thickness at a nanoscale range and the robust lattice structure that can withstand to the rigorous perforation methods render graphene to stand ahead of its contemporary materials. Moreover, its broad chemical tolerance and high mechanical strength facilitate the mass-production of membranes possessing macroscopic dimensions and their subsequent long-term operation under harsh environments. In this concise review, we complied and discussed the progress of gas-separation performance of graphene-based membranes with a prime focus on recent advancements in scalability, functionalization/modification along with the new manufacturing processes including the budding approaches through synthetic chemistry. The strategies implemented, the factors that influenced the membranes'performance and the corresponding transport mechanisms were highlighted in detail. In the end, we outlined the daunting challenges facing by these graphene-based membranes in realization of their prospects as well as the proposed measures for alleviating them.

“…With the rapid development of global economy and advance of human dependence on energy, large quantity of greenhouse gases (e.g., CO 2 ) is increasingly released into the atmosphere as the result of the consumption of huge proportion of fossil fuels such as coal and petroleum . In turn, it induces critical environmental problems, that is, greenhouse effect, acid rain, weather disasters, climate warming, sea level rise, and loss of biodiversity . Therefore, carbon dioxide capture has been attracting considerable attention especially for the widespread use of boiler, gas turbine, power plant, smelting furnace, and so forth .…”

CO 2 -selective Pebax/NaY mixed matrix membranes (MMMs) were prepared by incorporating NaY zeolite into Pebax matrix. The morphology, chemical groups, thermal stability, and microstructure of the MMMs were investigated by scanning electron microscope, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction, respectively. The effects of zeolite loading amount, permeation temperature and pressure on the CO 2 /N 2 separation performance of the resultant membranes were studied. The as-prepared MMMs are much superior to the pristine Pebax membranes in terms of permeability and selectivity. The CO 2 permeability and CO 2 /N 2 selectivity can respectively reach to 131.8 Barrer and 130.8 for MMMs made by the starting materials containing 40 wt % NaY.

“…Even though the experimental performance of MMMs did not overcome the performance for the pair of gases CO 2 /CH 4 reported in the literature, it is noteworthy the addition of 10 wt % of clinoptilolite impregnated with EA and BHPA represented an important approach to the upper bound. In addition, a comparison of the performance of some polysulfone‐based MMMs reported recently, and the MMMs reported in this work are listed in Table S1 . It could be seen that modified clinoptilolite could be considered as a good candidate to be used as filler in MMM to improve the CO 2 permeability and CO 2 /CH 4 selectivity.…”

Flat mixed matrix membranes (MMMs) comprising polysulfone and clinoptilolite-type natural zeolite were prepared by casting. Zeolite was modified with three alkylamines: ethanolamine (EA), bis(2-hydroxypropyl)amine (BHPA), and polyethylenimine (PEI) by the impregnation method. Impregnated zeolite samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and N 2 adsorption-desorption. The alkylamine loading extent determined by thermogravimetric analysis was 5.2, 4.8, and 8.5% for EA, BHPA, and PEI, respectively. Analyses of MMMs showed that the incorporation of impregnated zeolite affected the glasstransition temperature (T g ) and mixed-gas transport properties. In this regard, a decreasing trend of the T g values from 185.5 C for the polymeric membrane up to 176.6 C for Clino-EA-based MMM was recorded. In addition, the gas separation performance was evaluated at two different feed pressures. At 50 psi, MMMs showed an enhancement up to 30% on the CO 2 permeability (22.79 Barrer) and 55% on the CO 2 /CH 4 selectivity (45.78) in comparison with the polymeric membrane (CO 2 permeability 17.34 Barrer; CO 2 /CH 4 selectivity 29.38). These values varied depending on the alkylamine, BHPA being the most selective.
