“…We tabulated the measured or simulated performance of GO membranes as a function of membrane thickness or interlayer distance in Table S8. For example, Xue et al 76 examined the H 2 /CH 4 separation performance of GO membranes having different interlayer distances (5,6,7, and 8 Å). The optimum gas permeability performance was recorded at 6 Å for H 2 while it was 8 Å for CH 4 .…”

“…Considering the H 2 /CO 2 separation provided by these comprehensive studies, the highest H 2 permeability and H 2 /CO 2 selectivity were reported as 1.7 × 10 6 Barrer and 6.3, respectively. 29 Promisingly, 899 MOF membranes surpassed Robeson's upper bound and possessed H 2 permeability of >10 5 Barrer and H 2 /CO 2 selectivity above 2.27. 29 Likewise, 309 COFs for CO 2 /N 2 and H 2 /CO 2 as well as 589 COFs for He/H 2 , He/CH 4 , He/N 2 , H 2 /CH 4 , H 2 /N 2 , and N 2 /CH 4 were examined to unlock their membrane-based gas separation performance.…”

“…One such limitation is their tendency to undergo plasticization when exposed to condensable gases, as well as their susceptibility to aging phenomena. 5 these membranes is that their separation performance fails to surpass the Robeson upper bound due to the inherent trade-off between permeability and selectivity. 6 As a result, scientists are presently focused on creating innovative membranes that incorporate inorganic nanoporous nanomaterials.…”

In various industrial applications focusing on environmental sustainability, the purification of H2 from CO2-containing streams is crucial. Membrane-based separation processes are preferred over other gas separation techniques due to their superior efficiency and selectivity and lower energy consumption. Membranes composed of inorganic nanoporous materials, known for their uniform pore size distribution and high permeability, exhibit remarkable gas separation performance. Recently, two-dimensional (2D) nanomaterials with high surface area and tunable functional groups have gained attention for membrane-based gas separation applications, owing to their thermal and mechanical durability. Therefore, we carried out a simulation study at the nanoscale level encompassing multiple analytical viewpoints of 2D MXene membranes: (i) A collection of 730 MXene structures was evaluated for single gas H2/CO2 separation, and 700 of these surpassed the Robeson upper bound, indicating their significant potential for replacing conventional polymeric membranes. Moreover, VCrNF2, MoWCF2, Y2NO2, and Sc2NO2 nanomaterials were listed as potential membranes according to the predefined ranking criteria. (ii) The performance of mixed matrix membranes (MMMs) made of five different polymers and all MXene nanomaterials was calculated with Maxwell’s model. (iii) The effect of interlayer distance of MXene nanosheets on H2/CO2 separation was examined over the top four MXene nanomaterials and experimentally highly studied Ti2CO2 MXene. The optimum interlayer distance was defined as 5.5 Å for effective separation. (iv) Finally, Y2NO2 and Ti2CO2 MXene membranes were compared in terms of concentration polarization. Y2NO2 is more susceptible to CO2-related concentration polarization, which hinders CO2 transport and improves H2/CO2 separation in single gas measurements. By examining MXene membranes for H2/CO2 separation in multiple aspects, we aimed to demonstrate their potential and further guide the experimental studies.

“…3,4 Specifically, membranes have been intensively studied for separating small gas molecules (e.g., He and H 2 ) from larger gas molecules (e.g., CH 4 , CO 2 and N 2 ). 5,6 Compared to traditional separation technologies (e.g., adsorption, absorption, and cryogenic separation), membrane separation has advantages of low operating costs, smaller footprint, and easy maintenance. 7 Over the past decades, many different membrane materials have been developed for gas separation, such as polymeric membranes, 4,8 inorganic membranes (e.g., ceramic mem-branes), 9 mixed matrix membranes (MMMs), 10 membrane contactors, 11 thermal-rearranged (TR) membranes, 12 and carbon molecular sieve (CMS) membranes.…”

Carbon molecular sieve (CMS) membranes have been proven to be effective gas separation membranes, especially for light gas separation. In the current work, Troger's base polymer (TB)/poly(styrene sulfonic acid) (PSS) thin-film-composite (TFC) carbon molecular sieve (CMS) membranes were prepared by dip-coating and subsequent carbonization. Porous anodic aluminum oxide (AAO) plates were employed as the support layer, and carboxylated nanocellulose fiber (CNF) was used as the sacrificed layer. The effects of membrane preparation conditions, including solution concentration and carbonization temperature, and operating conditions, such as feed pressure and test temperature, on the hydrogen (H 2 ) and helium (He) separation performance were systematically investigated. Meanwhile, the relationship between gas separation performances and the microstructure of TFC CMS membranes was explored by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), and Raman spectrum. With a carbonization temperature of 550 °C, the H 2 /CH 4 (149.25), H 2 /N 2 (131.04), He/CH 4 (137.07), and He/N 2 (120.35) selectivity of the TB/PSS membrane prepared at a solution concentration of 10 wt % was significantly higher than other TFC CMS membranes, and the H 2 and He permeances were 1359.73 GPU and 1248.49 GPU under a feed pressure of 2 bar, respectively. The excellent gas separation performance of this membrane demonstrates its great potential for H 2 and He purification applications.

In the present study, the polyethersulfone (PES)/graphene oxide (GO)/polyethylene glycol 200 (PEG‐200) adsorptive mixed matrix membranes (AMMMs) were fabricated using a non‐solvent induced phase inversion method. According to the design of experiments using response surface methodology (RSM), PES concentration (15, 17.5, and 20%), PEG‐200 concentration as a pore former additive (0.5, 2.5, and 4.5%), and GO nanosheet loading percent (0, 0.5, and 1%) were varied during fabrication. A green solvent, dimethyl sulfoxide, was used as an alternative to conventional solvents, while it exhibited better membrane performance. Methylene blue (MB) removal was optimized in PES AMMM synthesis using RSM. Attenuated total reflectance Fourier transform infrared spectroscope confirmed the presence of GO functional groups in the optimum membrane. Scanning electron microscopy analysis revealed the optimum membrane was thicker than the neat membrane and atomic force microscopy analysis demonstrated higher surface roughness. The membranes hydrophilicity increased, with a decrease in water contact angle from 61.1 ± 0.2° (neat PES) to 54.4 ± 0.9° (optimal membrane). Pure water flux of 524.8 L m−2 h−1 and MB rejection of 97.46% were obtained for the optimum membrane. Furthermore, the optimum PES AMMM demonstrated a greater dynamic adsorption capacity in comparison to the unmodified PES membrane.Highlights The optimization of the polyethersulfone (PES) adsorptive mixed matrix membranes (AMMM) for methylene blue removal was performed utilizing the response surface methodology. The calculation of the dynamic adsorption capacity (DAC) was performed through the breakthrough curves. The integration of graphene oxide into the AMMM resulted in an enhanced DAC of the AMMM. The PES AMMM performance is based on Donnan electrostatic exclusion.
