Metal-organic frameworks (MOFs) have drawn significant attention in the fabrication of thin film nanocomposite (TFN) membranes. In particular, two-dimensional MOFs (2D-MOFs) are advantageous in improving compatibility and mol. sieving performance depending on the sub-at. surface thickness, high exposure of surface functional groups and controllable pore structure properties. In this study, a robust high performance TFN membrane for reverse osmosis (RO) desalination was fabricated using an interfacial polymerization strategy on the surface of polysulfone (PSF) substrate with embedded ultrasonically exfoliated nickel-based 2D-MOF nanosheet in the selective layer. The TFN membrane modified by adding 0.015 wt% 2D-MOF nanosheet to the aqueous phase exhibits a 2.5 times higher water permeability with a well-maintained salt rejection (water permeance up to 50.0 L m-2 h-1·MPa-1, NaCl rejection of 99.2%) compared to pristine thin film composite (TFC) membrane (water permeance 20.6 L m-2 h-1·MPa-1, NaCl rejection 99.3%). Meanwhile, the modified TFN membrane features outstanding anti-fouling properties against 500 ppm humic acid with a high water permeance recovery ratio of 96.9%. In addition, the diffusions of water mols. both in pristine TFC membrane and modified TFN membrane were investigated by the mol. dynamics (MD) simulation, showing good agreement with the exptl. results. The simulation results reveal that the incorporation of 2D-MOF nanosheets can reduce transfer resistance and increase water diffusion because of the extra pores of 2D-MOF and H bonds between free water mols. and the coordination water of 2D-MOF. This study presents a new strategy to fabricate high-performance RO membranes, and also provides further insights into the great potential of 2D-MOFs in the water-treatment field. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Product Details of 4422-95-1).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Product Details of 4422-95-1
