“…With increasing ZIF‐8 loadings in PSF, the separation performance of CO 2 and CH 4 was gradually increased towards the 1991 upper bound. Compared to the other ZIF8/PSF based MMMs reported in the recent literature, 26‐29 membranes fabricated in this work still demonstrated higher CO 2 /CH 4 gas pair selectivity and CO 2 gas permeability. The 1.0 wt% ZIF‐8/PSF MMM fabricated in this work exhibits the highest CO 2 permeability and CO 2 /CH 4 ideal selectivity in comparison with the results obtained for the PSF based MMMs reported in the literature 64‐66 .…”

“…for CO 2 /CH 4 separation and the highest CO 2 /CH 4 selectivity of 35 was achieved at a ZIF‐8 loading of 8 wt%. On the other hand, Anastasiou and co‐workers 28,29 reported the fabrication of mixed matrix membranes containing 5 wt% of ZIF‐8 and PSF via solvent‐evaporation method by using dimethylformamide as solvent. They found that CO 2 /CH 4 gas pair selectivity was decreased compared to the neat PSF membrane, which could be due to the excessive loading of fillers in the PSF matrix.…”

BACKGROUND Natural gas is essential for the world's supply of energy due to its economic viability and environmental sustainability in producing adequate amounts of clean energy. However, the removal of CO2 as an undesirable impurity remains challenging in natural gas purification. In this work, high performance dense mixed matrix membranes (MMMs) containing a low loading (<2 wt%) of zeolitic imidazolate framework 8 (ZIF‐8) and polysulfone (PSF) were prepared via simple solvent evaporation method and single solvent for the removal of CO2 from CH4. RESULTS Significant enhancements in CO2 permeability and CO2/CH4 ideal selectivity were obtained for the resultant MMMs as compared to the neat PSF membrane. The highest CO2 permeability of 33.57 Barrer and CO2/CH4 ideal selectivity of 39.03 were achieved for a PSF membrane loaded with 1 wt% of ZIF‐8; these values were 514% and 161% higher than those obtained for the neat PSF membrane, respectively. Furthermore, MMM embedded with 1 wt% of ZIF‐8 demonstrated CO2 plasticization pressure up to 16 bar, which is equivalent to an 100% increment of the value obtained for the neat PSF membrane. CONCLUSION Overall, MMMs fabricated in this work demonstrated a significant improvement of CO2 separation from CH4 compared to the PSF‐based MMMs reported in the literature, where most of the reported MMMs contain high loading of fillers up to 30 wt%. Therefore, the MMMs fabricated in this work are ready to be further exploited for application in gas separation industries. © 2021 Society of Chemical Industry (SCI).

Membrane technology is the most promising technology in the post-combustion capture technology compared to absorption, adsorption and cryogenic distillation methods. It is an advanced new technology for recovery of carbon dioxide. It has several advantages when compared to other methods due to its’ simple process, low cost, lower footprint, sustainable environment and energy saving method. The challenge is the fabrication method of the polymeric membrane, and it depends on the particular utilisation of the membrane. Different morphologies of the membrane structure can be produced using different methods.

“…Zeolite has a high adsorption capacity for higher CO 2 partial pressure, when compared with other adsorbents. However, due to competitive adsorption, low CO 2 adsorption capacity in the presence of water is often observed due to high affinity of these materials for water [12]. Membranes, on the other hand, provide better performance due to their properties and processability, but efforts to improve permeability are usually made to the detriment of selectivity and vice versa [7].…”

“…To improve the performance of polymeric membranes, various resolutions have been proposed with particular importance on International Journal of Chemical Engineering exploiting the selectivity size or shape provided by dispersed nanoporous materials in combination with the polymer processability and mechanical stability. To this end, various polymers were modified with inorganic fillers to evenly disperse the filler particles in a polymer matrix to give a mixed matrix membrane (MMM) [12]. Glassy-polymers generally lead to MMMs with improved release characteristics, while highly permeable and poorly selective gummy polymers are unlikely to be effective as MMMs when inorganic fillers are used.…”

The adoption of nanodoped membranes in the areas of gas stream separation, water, and wastewater treatments due to the physical and operational advantages of such membranes has significantly increased. The literature has shown that the surface structure and physicochemical properties of nanodoped membranes contribute significantly to the interaction and rejection characteristics when compared to bare membranes. This study reviews the recent developments on nanodoped membranes, and their hybrids for carbon capture and gas separation operations. Features such as the nanoparticles/materials and hybrids used for membrane doping and the effect of physicochemical properties and water vapour in nanodoped membrane performance for carbon capture are discussed. The highlights of this review show that nanodoped membrane is a facile modification technique which improves the membrane performance in most cases and holds a great potential for carbon capture. Membrane module design and material, thickness, structure, and configuration were identified as key factors that contribute directly, to nanodoped membrane performance. This study also affirms that the three core parameters satisfied before turning a microporous material into a membrane are as follows: high permeability and selectivity, ease of fabrication, and robust structure. From the findings, it is also observed that the application of smart models and knowledge-based systems have not been extensively studied in nanoparticle-/material-doped membranes. More studies are encouraged because technical improvements are needed in order to achieve high performance of carbon capture using nanodoped membranes, as well as improving their durability, permeability, and selectivity of the membrane.
