“…Since this utilises polymeric properties, the majority of MMMs (3%) are made from different types of polymer materials but face commercialisation issues on a large scale. Metal-organic frameworks (MOFs, n = 14, 3%) [211,[248][249][250][251][252][253][254][255][256][257][258][259][260] are one of the recent inventive solutions for CO 2 separation, with 14 studies exploring the potential. The physical characteristics such as high porosity and surface area along with adjustable pore size and versatile structural arrangement makes it an ideal membrane.…”

With fossil fuel being the major source of energy, CO2 emission levels need to be reduced to a minimal amount namely from anthropogenic sources. Energy consumption is expected to rise by 48% in the next 30 years, and global warming is becoming an alarming issue which needs to be addressed on a thorough technical basis. Nonetheless, exploring CO2 capture using membrane contactor technology has shown great potential to be applied and utilised by industry to deal with post- and pre-combustion of CO2. A systematic review of the literature has been conducted to analyse and assess CO2 removal using membrane contactors for capturing techniques in industrial processes. The review began with a total of 2650 papers, which were obtained from three major databases, and then were excluded down to a final number of 525 papers following a defined set of criteria. The results showed that the use of hollow fibre membranes have demonstrated popularity, as well as the use of amine solvents for CO2 removal. This current systematic review in CO2 removal and capture is an important milestone in the synthesis of up to date research with the potential to serve as a benchmark databank for further research in similar areas of work. This study provides the first systematic enquiry in the evidence to research further sustainable methods to capture and separate CO2.

“…Graphene -based membranes for CO 2 separation purposes have been considered in the literature both using neat graphene as separation media, i.e. engineering graphene porosity, 3132,33,34 or with graphene acting as support for CO 2 capturing materials, especially for ambient temperature molten salts (i.e. ionic liquids).…”

The properties and structure of relevant interfaces involving molten alkali carbonates are studied using molecular dynamics simulations. Lithium carbonate and the Li/Na/K carbonate eutectic mixture are considered. Gas phase composed of pure CO 2 or a model flue gas mixture are analysed. Likewise, the adsorption of these gas phases on graphene are studied, showing competitive CO 2 and N 2 adsorption that develops liquid-like layers and damped oscillation behaviour for density. The interaction of the studied carbonates with graphene is also characterized by development of adsorption layers through strong graphene-carbonate interactions and the development of hexagonal lattice arrangements, especially for lithium carbonate. The development of molten salts-vacuum interfaces is also considered, analysing the ionic rearrangement in the interfacial region. The behaviour of the selected gas phases on top of molten alkyl carbonate is also studied, showing the preferential adsorption of CO 2 molecules when flue gases are considered.

“…The repulsion effect of the crystal growth of ZIFs on the GO plate can improve the rigidity of the plates and extend them significantly, as shown in Figure (b). More specifically, the fewer folding interlayer channels are still conducive to improving the gas diffusion selectivity caused by the tortuous pathways, and the uniform dispersion of ZIFs@GO offers the potential for permeability enhancement, as shown in Figure 6(c). Moreover, the ZIF textural structure is a useful addition here, as mentioned in the previous section.…”

Mixed matrix membranes (MMMs), which combine the good separation performance of inorganic materials with the low cost of polymers, have emerged as a research hotspot for gas separation membranes. Zeolite imidazolate frameworks (ZIFs) are widely used as fillers to prepare MMMs owing to their advantageous characteristics, such as adjustable pore channels, unsaturated sites, and easy functionalization. For MMMs, three directions can be employed as criteria for improvement compared with pristine polymeric membranes. In this article, the progress of ZIF-based MMMs is reviewed from the aspects of sole-ZIF-based MMMs and modified ZIFbased MMMs. Both strategies improve the separation performance through different improvement directions and mechanisms. Our analysis shows that the synergistic effect of the modified filler can change the structure of the membranes, such as by improving the filler-polymer interface voids, which provides a foundation to overcome the trade-off effect to a certain extent.
