“…XRD patterns of the bulk Cu-TCPP and t -Cu-TCPP samples are shown in Figure a. The characteristic diffraction peaks at 7.5, 8.8, 11.9, and 19.3° were well matched with the (110), (002), (210), and (004) planes of the Cu-TCPP phase, revealing the successful fabrication of Cu-TCPP. , Moreover, the t -Cu-TCPP sample exhibited almost identical XRD patterns to the bulk Cu-TCPP sample. This indicated that Cu-TCPP is stable during ultrasonication treatment in water.…”

“…The FTIR spectra of the bulk Cu-TCPP and t -Cu-TCPP nanosheets are compared in Figure b. The FTIR spectra of the two Cu-TCPP samples give two distinguished peaks at 1606 and 1403 cm –1 that are corresponding to vibrations of OC–O–Cu bonds, indicating the coordination interactions between COOH of porphyrin rings and Cu 2+ cations. , In addition, the sharp IR band at 3416 cm –1 represents free N –H in Cu-TCPP, indicating that N in the ligands did not form coordination with metal ions …”

The development of highly permeable and selective thin-film composite (TFC) membranes is essential for organic solvent nanofiltration (OSN) applications. However, overcoming the permeability–selectivity trade-off in polymer membranes remains highly challenging owing to the difficulty in controlling the thickness and nanostructures of the selective layers. In this study, TFC OSN membranes with sandwich-like structures were developed via interfacial polymerization on Cu-TCPP nanosheet-modified microporous polyvinylidene fluoride (PVDF) substrate surface. The interfacial polymerization was done by using mixed amine (polyethyleneimine and piperazine) in the aqueous phase and the 1,3,5-benzenetricarbonyl trichloride in the hydrophobic ionic liquid phase as monomers. It was found that the Cu-TCPP nanosheets of micrometer lateral dimensions and nanometer thickness (1.5 ± 0.6 nm) can be deposited on the PVDF substrate as an interlayer to facilitate the following interfacial polymerization reaction. The Cu-TCPP interlayer also can be served as a binder between the polyamide selective layer and the microporous PVDF substrate to enhance their mechanical strength. As compared with the PVDF/PA membrane, the PVDF/t-Cu-TCPP/PA membrane exhibited higher elongation (8.0 vs. 4.6%) while ensuring slightly lower tensile strength (36.0 vs. 48.6 MPa). Under optimal synthetic conditions, the TFC membranes could achieve 2.7 L m–2 h–1 bar–1, and 98.9% and 95.0% rejection to Brilliant Blue R (826 Da) and Congo red (697 Da), respectively, in ethanol. Furthermore, the membranes showed steady performance throughout the 36 h nanofiltration of the Rose bengal/ethanol mixture and exhibited good performance in the concentration of lecithin in methanol. Accordingly, this work highlights the potential of using thin metal–organic framework nanosheets as interlayers to develop high-performance TFC membranes for OSN applications.

“…Currently, MOF-based mixed-matrix membranes mainly adopt two methods: 1) direct addition of pre-synthesized MOF nanoparticles into the casting solution, followed by phase conversion into films, and 2) growth of MOF particles in situ in the casting solution, followed by transformation into films. Recently, Yao et al [137] synthesized M-TCPP/P84 MMMs using the knifecasting method. Compared to the original P84 membrane, the M-TCPP/P84 MMMs exhibited better permeability and marginally reduced retention.…”

Abstract2D metal‐organic frameworks‐based (2D MOF‐related) materials benefit from variable topological structures, plentiful open active sites, and high specific surface areas, demonstrating promising applications in gas storage, adsorption and separation, energy conversion, and other domains. In recent years, researchers have innovatively designed multiple strategies to avoid the adverse effects of conventional methods on the synthesis of high‐quality 2D MOFs. This review focuses on the latest advances in creative synthesis techniques for 2D MOF‐related materials from both the top‐down and bottom‐up perspectives. Subsequently, the strategies are categorized and summarized for synthesizing 2D MOF‐related composites and their derivatives. Finally, the current challenges are highlighted faced by 2D MOF‐related materials and some targeted recommendations are put forward to inspire researchers to investigate more effective synthesis methods.

Metal‐organic frameworks (MOFs) are an exceptional class of crystalline materials that have been extensively used to fabricate membranes for various applications such as gas separation, ion transport, and desalination due to their well‐defined pore structure, chemical features, and simple synthesis process. The incorporation of graphitic carbon materials in MOFs has garnered significant attention as it can provide abundant nucleation sites and modulate gas transport by influencing the orientation or rigidity of MOF crystals without changing their porous structure. This review insights of previous studies utilizing graphene, graphene oxide, carbon nanotubes, and graphene nanoribbons for MOF‐based gas separation membranes, particularly focusing on polycrystalline MOF membrane hybridization with graphitic materials. We also briefly discuss the use of carbon/MOF hybrid materials for preparing mixed matrix membranes.
