In this study, molecular dynamics simulation is used to investigate the effects of water-based substitutional defects in zeolitic imidazolate frameworks (ZIF)-8 membranes on their reverse osmosis (RO) desalination performance. ZIF-8 unit cells containing up three defect sites are construct membranes. These can either be Zn or linker defects. The RO performance assessed terms water flux and ion ...

In this article, we have investigated the role of dimethylamine (DMA), tributylamine (TBA), Triethanoleamine (TEA), Trishydroxymethylamine (TRIZMA), and Hexamethyleneterraamine (HMTA), in the formation of zeolitic compounds. The experiments were carried out in acidic and basic media using Si/Al< 10 and Si/A1>10. The structure of the resulting synthetic zeolites were similar to Natro Davyne,...

A novel biobased porous aerogel was synthesized using physical mixing, freeze-drying, and in-situ growth methods. Zeolitic imidazolate frameworks-8 (ZIF-8) were grafted onto the surface of CS/CNF solid composite to form a ZIF-8@CS/CNF aerogel. The structural characteristics adsorption potential investigated. It found that specific area 206 m2/g, water stability CNF enhanced by incorporating CS....

Constructing an interlayer between porous substrate and polyamide (PA) film is effective strategy to overcome the ubiquitous trade-off permeability selectivity, which are both important properties for nanofiltration performance. In this study, a poly(sodium 4-styrenesulfonate) (PSS) assisted interfacial synthesis method was proposed fabricate zeolitic imidazolate framework-8 (ZIF-8) PA micropor...

Using a combination of molecular simulations techniques, we evaluate the structural tunability metal azolate framework with zeolitic RHO topology, MAF-6. Two mechanisms are explored to induce hydrophilicity this hydrophobic material. The study at level water adsorption takes place under variety conditions. On first step, consider mixtures containing benzene or alcohols, paying special attention...

Here we report a highly porous, water stable Co based ZIF [CoNIm (RHO)] and its solution mediated phase transformation to a less porous and water unstable ZIF [CoNIm (SOD)]. CoNIm (RHO) has high Langmuir surface area [2087 m(2) g(-1)] as well as high water adsorption [200 cm(3) (STP) g(-1)] capacity.
