“…19,20 The permeabilities of silicalite were highest. For zeolite NaA-filled PDMS membranes, the permeability of O 2 was higher while that of CO 2 was lower than those in clinoptilolitefilled PDMS membranes.…”

“…PDMS was selected as the polymer since its mixed matrix membranes with zeolites may be prepared without any surface modification of the zeolite and there are no adhesion problems, as observed in previous studies performed by using ZSM-5, silicalite, and NaA-filled PDMS membranes. 19,20 Accordingly, the natural zeolite was ion-exchanged to obtain its forms rich in Na, K, Mg, and H. The zeolite-polymer mixed matrix membranes were prepared by a casting-evaporation process. The characterizations of the membranes were performed by the measurements of the O 2 , N 2 , and CO 2 gas permeabilities as well as scanning electron microscopy (SEM).…”

Zeolite-polymer mixed matrix membranes were prepared by filling polydimethylsiloxane (PDMS) with clinoptilolite in various cationic forms of K, Mg, H, and Na. The membranes were characterized by scanning electron microscopy as well as measurements of O 2 , N 2 , and CO 2 gas permeabilities. The results indicated the presence of an optimum zeolite loading in the mixed matrix membranes maximizing permeability. The type of the cationic form of clinoptilolite used affected the permeabilities and ideal selectivities of the zeolite-polymer mixed matrix membranes investigated to some degree and some improvements were obtained when compared to the ideal selectivities of the original polymeric membranes.

“…Therefore, it is highly desirable to provide an alternate cost-effective nanomembrane in a position above the trade-off curves between permeability and selectivity [19]. Mixed-matrix membranes (MMMs) are considered as hybrid membranes containing liquid, solid, or both liquid and solid fillers embedded in a polymer matrix [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. They are densely packed polymer membranes with organic or inorganic nanoparticles introduced into their structure.…”

“…Also, the gas permeation properties of the CMS particles can be tailored by modifying pyrolysis procedure, which makes mixed matrix membranes containing CMS more adaptable for desired gas separations. Tantekin-Ersolmaz et al [189] reported that the permeabilities of the silicalite-PDMS mixed matrix membranes increased with increasing zeolite particle size while the CO 2 /N 2 permselectivities remained unaffected. They also stated that the effect of particle size was more pronounced at the higher zeolite loading.…”

The atmospheric concentration of anthropogenic carbon dioxide (CO 2 ) has been increasing since the start of industrialization in the mid 19th century, and the rate is increasing. It is highly unlikely that fossil fuel combustion, the main contributor to anthropogenic CO 2 , will be replaced in the foreseeable future. Therefore, CO 2 capture and storage offer a new set of options for reducing greenhouse gas emissions, in addition to the current strategies of improving energy efficiency and increasing the use of renewable energy resources. Carbon dioxide selective membranes provide a viable energy-saving alternative for CO 2 separation, since membranes do not require any phase transformation. This review examines various CO 2 selective membranes for the separation of CO 2 and N 2 , CO 2 and CH 4 , and CO 2 and H 2 from flue or fuel gas. This review attempts to summarize recent significant advances reported in the literature about various CO 2 selective membranes, their stability, the effect of different parameters on the performance of the membrane, the structure and permeation properties relationships, and the transport mechanism applied in different CO 2 selective membranes. Finally, the future direction for CO 2 selective membranes is proposed. Hybrid organic-inorganic membranes have become an expanding field of research, as the introduction of organic molecules can improve the characteristics of a matrix. Hydrotalcite-type materials, perovskite-type oxides, lithium zirconate, and lithium silicate are also suggested as candidate materials for high temperature CO 2 selective membranes.
