This study investigates the production and performance of a novel nanofiltration membrane for removal cationic dye (Methylene blue) multivalent cations. These positively charged membranes are made by dispersing modified metal–organic framework, Cl-MIL-101(Cr), into polyvinyl alcohol matrix as skin layer. To this end, mobile anion (Cl−) embedded in MIL-101(Cr) structure plays role to create posi...
We present the in situ synthesis of Pt nanoparticles within MIL-101-Cr (MIL = Materials Institute Lavoisier) by means of atomic layer deposition (ALD). The obtained Pt@MIL-101 materials were characterized by means of N₂ adsorption and X-ray powder diffraction (XRPD) measurements, showing that the structure of the metal organic framework was well preserved during the ALD deposition. X-ray fluore...
Low-coverage adsorption properties of the metal-organic framework amino-MIL-53 (Al) were determined using the pulse chromatographic technique. By using n-alkanes, iso-alkanes, 1-alkenes, cyclohexane and benzene as probe molecules, the nature of the adsorptive interactions in amino-MIL-53 (Al) was studied. Henry adsorption constants and adsorption enthalpies of iso-alkanes are significantly lowe...
در این رساله به بررسی عملکرد غشاهای شبکه ترکیبی pmp/mil 53 و pmp/nh2-mil 53 در جداسازی گازهای co2/ch4 و co2/h2 پرداخته شده است. به منظور مشخصه¬یابی ذرات mof و غشاهای حاصله از روش¬های xrd، ft-ir، tga، dma، dls، sem،¬ bet و آزمون جذب گاز استفاده شد. همچنین خواص گاز تراوایی غشاها با عبور گازهای خالص و مخلوط¬های گازی و محاسبه تراوایی، گزینش¬پذیری¬های¬ ایده¬آل و واقعی و محاسبه ضرایب نفوذ و حلالیت سن...
In this study, the hydrothermal method was used to synthesize MIL-101(Cr), and activated carbon (AC) with different content incorporated in thereby obtaining AC-MIL-101(Cr) composite material a huge specific surface area. The physical properties of MIL-101(Cr) were characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), nitrogen ad...
The synthesis on the gram scale and characterization of a series of flexible functionalized iron terephthalate MIL-53(Fe) type solids are reported. Chemical groups of various polarities, hydrophilicities, and acidities (-Cl, -Br, -CF(3), -CH(3), -NH(2), -OH, -CO(2)H) were introduced through the aromatic linker, to systematically modify the pore surface. X-ray powder diffraction (XRPD), molecula...
BACKGROUND Metal organic frameworks (MOFs) have attracted more attention in the last decade because of a suitable pore size, large surface area, and high pore volume. Developing biocompatible MOFs such as the MIL family as a drug delivery system is possible. PURPOSE Flurbiprofen (FBP), a nonsteroidal anti-inflammatory agent, is practically insoluble in aqueous solution, and, therefore, needs ...
H3PMo12O40 molecules have been successfully encapsulated in the cavities of MIL-100(Fe) via a facile hydrothermal method (denoted as HPMo@MIL-100(Fe)). A series of characterization has corroborated the insertion of H3PMo12O40 within the cavities of MIL-100(Fe). The resulting HPMo@MIL-100(Fe) nanocomposites have exhibited much higher photoactivity than the original-MIL-100(Fe) toward the photoca...
