“…Relating to the use of zeolites to increase MWCNT–MMM performance, some studies showed high separation performance of CO 2 [ 101 ]; these results were confirmed in an additional study involving CO 2 removal from post-combustion flue gas. An additional advantage of using zeolites is the fact that MMMs can operate in wet conditions compared to usually dry conditions having, at the same time, selectivity above Robeson’s upper limit [ 104 ].…”

The membranes’ role is of supreme importance in the separation of compounds under different phases of matter. The topic addressed here is based on the use of membranes on the gases separation, specifically the advantages of mixed-matrix membranes (MMMs) when using carbon nanotubes as fillers to separate carbon dioxide (CO2) from other carrier gas. MMMs consist of a polymer support with additive fillers to improve their efficiency by increasing both selectivity and permeability. The most promising fillers in the MMM development are nanostructured molecules. Due to the good prospects of carbon nanotubes (CNTs) as MMM fillers, this article aims to concentrate the advances and developments of CNT–MMM to separate gases, such as CO2. The influence of functionalized CNT or mixtures of CNT with additional materials such as zeolites, hydrogel and, graphene sheets on membranes performance is highlighted in the present work.

Gas separation and purification using polymeric membranes is a promising technology that constitutes an energy-efficient and eco-friendly process for large scale integration. However, pristine polymeric membranes typically suffer from the trade-off between permeability and selectivity represented by the Robeson's upper bound. Mixed matrix membranes (MMMs) synthesized by the addition of porous nano-fillers into polymer matrices, can enable a simultaneous increase in selectivity and permeability. Among the various porous fillers, metal-organic frameworks (MOFs) are recognized in recent days as a promising filler material for the fabrication of MMMs. In this article, we review representative examples of MMMs prepared by dispersion of MOFs into polymer matrices or by deposition on the surface of polymeric membranes. Addition of MOFs into other continuous phases, such as ionic liquids, are also included. CO 2 separation from hydrocarbons, H 2 , N 2 , and the like is emphasized. Hybrid fillers based on composites of MOFs with other nanomaterials, e.g., of MOF/GO, MOF/CNTs, and functionalized MOFs, are also presented and discussed. Synergetic effects and the result of interactions between filler/matrix and filler/filler are reviewed, and the impact of filler and matrix types and compositions, filler loading, surface area, porosity, pore sizes, and surface functionalities on tuning permeability are discoursed. Finally, selectivity, thermal, chemical, and mechanical stability of the resulting MMMs are analyzed. The review concludes with a perspective of up-scaling of such systems for CO 2 separation, including an overview of the most promising MMM systems.

“…According to Wang and Wang (2016) and Plechkova and Seddon (2008), although several chemical and physical properties of ILs and PILs have yet to be discovered, these ionic species possess distinct properties, including negligible volatility, high stability, high ionic conductivity, high polarity, and good solubility. Hence, they have been applied to carbon engineered nanocomposites, in innovative synthesis processes, and used as CO 2 blockers with elevated capacity of capture in the form of photocatalysts, mixed-matrix membranes (MMMs), bubble column additives, gaseous adsorbents, among others (Sarfraz and Ba-Shammakh, 2018;Tamilarasan and Ramaprabhu, 2015). Organic polymeric compounds are also applied in both covalent and noncovalent functionalization; though it depends on the strength and nature of their bonds to the graphene basal planes (Xiang et al, 2016;Yang et al, 2013b).…”

“…Between the treatments indicated to avoid emissions of gaseous pollutants into the atmosphere, one can cite: gas-liquid absorption Horikawa et al, 2004), photocatalytic reduction Sakakura et al, 2007), gas washing Liao and Siddoway, 1996), bio-, micro-and nanofiltration (Sarfraz and Ba-Shammakh, 2018;Soreanu et al, 2013;Montebello et al, 2012) and gas-solid adsorption (Yuan et al, 2018;Lalitha et al, 2017). However, gas-liquid absorption is one of the most effective processes to treat gaseous pollutants and decrease the emission of greenhouse effect gases in the atmosphere.…”

The functionalization of graphene nanosheets is the cutting edge of materials sciences nowadays. Such research promotes the development of innovative, low cost and highly capable sorbents. This review article aims to assemble the available information on functionalized graphene used for the adsorption of organic pollutants and establishes a critical comparison between the data reported in the literature. Various optimal experimental conditions (pH, temperature, contact time, adsorbent dosage) and adsorbent characterization methods (FTIR, Raman, XPS spectra, XRD, TEM and AFM) have been listed to enlighten adsorption mechanisms, capacity and limiting aspects. Moreover, adsorption isotherms, kinetics and thermodynamic data of different functionalized graphene-based materials towards a wide range of organic pollutants were analyzed and tabulated. In each evaluation topic, environmental and human health protection is subject for discussion, as well as the scientific breakthrough works available in high impact journals in the field.
