“…Despite having good traits of polymeric membrane and inorganic membrane, poor compatibility between filler particles and polymeric matrix has become one of the main challenges in MMMs. 7 Such condition leads to the formation of non-selective pathways at the polymerfiller interface. This type of morphology increases the permeability of all gas molecules, hence deteriorating its selectivity.…”

It is known that mixed‐matrix membranes (MMMs) suffer from poor compatibility between the polymer and inorganic phases. As a result, suboptimal morphology of a membrane is obtained. This study fabricated MMMs containing ZIF‐L as the inorganic filler and polyethersulfone (PES) via the thermally induced phase separation method. ZIF‐L loading was varied from .25 to 10.0 wt% to study the effect of ZIF‐L loading on the characteristic of the MMMs and gas separation performance (CO2/N2 and CO2/CH4). Unmodified ZIF‐L resulted in significant permeability and selectivity trade‐offs. To improve the compatibility between the components and affinity towards CO2, ionic liquid (IL) was introduced. Two methods of IL modification methods were tested. They are pre‐modification of ZIF‐L and post‐modification of PES/ZIF‐L MMMs. The findings revealed that the pre‐modification method has successfully sealed the polymer/filler interfacial void compared to post‐modification. It was found that the pre‐modification method has enhanced PES/ZIF‐L membrane's performance due to the minimal interfacial defects issue at low loading; 0.75 wt% of pre‐modified ZIF‐L in the PES matrix has enhanced the permeability of CO2 by more than eight times. Furthermore, the ideal CO2/N2 and CO2/CH4 selectivity recorded at this condition is 30.1 and 21.8, respectively. On the contrary, the post‐modification strategy turns out to be counterproductive.

“…Although in this study, the orientation of the nanosheet was not expected to be perpendicular to the gas diffusional path as the membrane was fabricated through the typical solvent evaporation method. The orientation was most likely randomized [ 20 ]. The high aspect ratio of the nanosheet filler increased the tortuosity of the diffusional path for the gas penetrant to pass through the dense selective layer of the membranes.…”

“…Recently, two-dimensional (2D) materials have received increasing attention in MMM fabrication due to their potential of exhibiting barrier properties when they are horizontally aligned, thus improving the selectivity of the MMM [ 18 , 19 ]. However, aligning the 2D nanosheet inside the polymer membrane matrix fabricated through typical physical blending still remains a challenge [ 20 ].…”

Carbon dioxide (CO2) concentration is now 50% higher than in the preindustrial period and efforts to reduce CO2 emission through carbon capture and utilization (CCU) are blooming. Membranes are one of the attractive alternatives for such application. In this study, a rubbery polymer polydimethylsiloxane (PDMS) membrane is incorporated with magnesium oxide (MgO) with a hierarchically two-dimensional (2D) nanosheet shape for CO2 separation. The average thickness of the synthesized MgO nanosheet in this study is 35.3 ± 1.5 nm. Based on the pure gas separation performance, the optimal loading obtained is at 1 wt.% where there is no observable significant agglomeration. CO2 permeability was reduced from 2382 Barrer to 1929 Barrer while CO2/N2 selectivity increased from only 11.4 to 12.7, and CO2/CH4 remained relatively constant when the MMM was operated at 2 bar and 25 °C. Sedimentation of the filler was observed when the loading was further increased to 5 wt.%, forming interfacial defects on the bottom side of the membrane and causing increased CO2 gas permeability from 1929 Barrer to 2104 Barrer as compared to filler loading at 1 wt.%, whereas the CO2/N2 ideal selectivity increased from 12.1 to 15.0. Additionally, this study shows that there was no significant impact of pressure on separation performance. There was a linear decline of CO2 permeability with increasing upstream pressure while there were no changes to the CO2/N2 and CO2/CH4 selectivity.

“…Mixed matrix membrane (MMM), with rigid permeable or impermeable particles (e.g., zeolites, carbon molecular sieves, silica and carbon nanotubes) dispersed in their polymer‐based frameworks, could greatly improve the separation properties of polymeric membranes. [ 73,74 ] Shao et al. designed a DMSNs‐stimulated MMM towards superior CO 2 capture, as shown in Figure 3d.…”

Dendritic mesoporous silica nanoparticles own three‐dimensional center‐radial channels and hierarchical pores, which endows themselves with super‐high specific surface area, extremely large pore volumes, especially accessible internal spaces, and so forth. Dissimilar guest species (such as organic groups or metal nanoparticles) could be readily decorated onto the interfaces of the channels and pores, realizing the functionalization of dendritic mesoporous silica nanoparticles for targeted applications. As adsorbents and catalysts, dendritic mesoporous silica nanoparticles‐based materials have experienced nonignorable development in CO2 capture and catalytic conversion. This comprehensive review provides a critical survey on this pregnant subject, summarizing the designed construction of novel dendritic mesoporous silica nanoparticles‐based materials, the involved chemical reactions (such as CO2 methanation, dry reforming of CH4), the value‐added chemicals from CO2 (such as cyclic carbonates, 2‐oxazolidinones, quinazoline‐2,4(1H,3H)‐diones), and so on. The adsorptive and catalytic performances have been compared with traditional silica mesoporous materials (such as SBA‐15 or MCM‐41), and the corresponding reaction mechanisms have been thoroughly revealed. It is sincerely expected that the in‐depth discussion could give materials scientists certain inspiration to design brand‐new dendritic mesoporous silica nanoparticles‐based materials with superior capabilities towards CO2 capture, utilization, and storage.
