The use of thin film composites containing metal–organic frameworks (MOFs) as filler is of widespread interest for nanofiltration issues, since their thin selective layer allows a high permeation flow. The application of this kind of membranes for gas separation should provide a better permeance in comparison with other polymeric membranes and a reduction in the amount of MOF required for their fabrication. Here, the preparation of 50–100 nm thick polyamide flat membranes containing zeolitic imidazolate framework‐8 (ZIF‐8) nanoparticles is shown via interfacial polymerization, containing a lower amount of MOF (0.013 g m−2 membrane) as compared to other membranes used for gas separation. The membranes are applied for H2/CO2 separation at high temperatures and pressures, showing a stable performance at 180 °C for at least seven days. Outstanding separation values are 328 GPU of H2 and a H2/CO2 selectivity of 18.1 at 180 °C and 6 bar feed without transmembrane pressure. These membranes, also measurable without sweep gas, are highly suitable for industrial application.

“…Not only high electroactivity can be achieved on derivatives from a single ZIF‐8, ZIF‐8 hybridized with other ZIFs with matched topology brings new insights into the derivations with improved properties, such works have been conducted on ZIF‐7, ZIF‐9, ZIF‐90, and ZIF‐67 . A hierarchical carbon nanopolyhedra (Co, N‐HCNP) was synthesized by co‐doping cobalt and nitrogen via the carbonization of core‐shell structured ZIF‐8@ZIF‐67 crystals.…”

Metal-organic frameworks (MOFs) have been intensely studied for the past few decades as an enormous family of highly tunable porous materials with promisingly applicable functionalities in adsorption, separation, catalysis, sensing, electrochemistry, and a great number of emerging purposes. As a classic MOF, zeolitic imidazolate framework-8 (ZIF-8) is conventionally one of the very few MOF members that has been commercialized with considerable production. Its large surface areas, well-controlled porosity and textural tunability, high thermal and chemical stability allows researchers to conduct enormous studies on derivatives of MOFs and MOF-related composites using ZIF-8 as the prior sampling substance. However, despite all the remarkable discoveries leading almost all aspects of future applications of MOFs, no specific work has yet been done to recapitulatively summarize these achievements centered around the current limitations and prospects of their common demonstrator, ZIF-8, for its integration into real processes or applications, thus drastically blinding people from distinctly observing the inner correlations among all these researches. To wipe out this confusion and make the usages of ZIF-8 both in applicable systems and upfront explorations much more understandable and convenient to all researches of relevant application areas, this review aims at offering clear guidance, experience, and references by meticulously categorizing published works associated with ZIF-8.

“…The amino-functionalized MOFs filled MMMs have been also fabricated by Seoane et al and the membrane performance was improved approaching the Robeson CO 2 /CH 4 and H 2 /CH 4 upper bound with 10 wt% MOFs loading [22]. In addition, other researchers have fabricated mixed matrix composite membrane by synthesizing MOFs continuous membrane on outer-side or inner-side of hollow fiber membrane to improve gas separation performance [23][24][25][26]. However, the filler particle aggregation and interfacial isolation are the major drawbacks that hinder the development of inorganic filler based MMMs [27,28].…”

The metal-organic framework (MOFs) of MIL-53 was functionalized by aminosilane grafting and then incorporated into Ultem®1000 polymer matrix to fabricate mixed matrix hollow fiber membrane (MMHFM) with high separation performance. SEM, XRD, and TGA were performed to characterize the functionalized MIL-53 and prepared MMHFM. The filler particles were embedded in membrane successfully and dispersed well in the polymer matrix. The incorporation of MOFs endowed MMHFM better thermal stability. Moreover, effects of solvent ratio in spinning dope, spinning condition, and testing temperature on gas separation performance of MMHFM were investigated. By optimizing dope composition, air gap distance, and bore fluid composition, MMHFM containing functionalized MIL-53 achieved excellent gas permeance and CO2/N2selectivity. The CO2permeance increased from 12.2 GPU for pure Ultem HFM to 30.9 GPU and the ideal CO2/N2selectivity was enhanced from 25.4 to 34.7 simultaneously. Additionally, gas permeance increased but the selectivity decreased with the temperature increase, which followed the solution-diffusion based transport mechanism.
