Mixed matrix membrane used to selective removal of CO2 was considered as an efficient solution to energy and environmental sustainability. In this study, a MMM that consists of amide functionalized porous coordination polymer filler (MIL-53-NH2) was successfully prepared, which sharply promotes the CO2/N2 selectivity from 44 (neat polymeric membrane) to 75. Remarkably, the positive effect of am...
سه چارچوب فلز-آلی (mof) نانو متخلخل از آهن (iii) با 2-آمینوترفتالیک اسید و ترفتالیک اسید، (fe-mil-101-nh2) (1) و (fe-mil-53) (2) و (fe-mil-53-nh2) (3)، در چارچوب فلز-آلی نانو متخلخل از کروم (iii) با ترفتالیک اسید، (cr-mil-53) (4) و (cr-mil-101) (5)، یک چارچوب فلز-آلی نانو متخلخل از منگنز (ii) با 5،3،1 بنزن تری کربوکسیلیک اسید h2o، {(ch3)2 nh2} {mn3(btc) (hcoo)4 (h2o)} (6)، به روش سالووترمال و ی...
The flexibility of eight aluminium hydroxo terephthalates [Al(OH)(BDC-X)]·n(guest) (BDC = 1,4-benzene-dicarboxylate; X = -H, -CH3, -Cl, -Br, -NH2, -NO2, -(OH)2, -CO2H) crystallising in the MIL-53-type structure was investigated upon thermal dehydration of as-made samples, superhydration and methanol adsorption/desorption using in situ powder X-ray diffraction (PXRD). Profile fitting was used to...
The MOFs selected in this work are NH2-MIL-53(Al), MIL-100(Fe) and UiO-66 type (Zr-BDC NH2-Zr-BDC). We have tried to assist the sustainable synthesis of MOFs, at room temperature water as a solvent, with presence non-ionic surfactants: Pluronic F127 P123. parent prepared solvent commonly grow form agglomerates small crystallites all cases. X ray diffraction patterns surfactant templated NH2-MIL...
در این پژوهش، اثر چارچوب های فلزی-آلی NH2-MIL 53 بر خواص گازتراوایی غشای پلیمری پلی(4- متیل-1- پنتین) (PMP) بررسی شده است. از روش های مختلفی نظیر FTIR، DSC، SEM و آزمون جذب گاز به همراه آزمون جداسازی CO2/CH4 به حالت گاز خالص و مخلوط گازی برای بررسی آثار گروه عاملی NH2- بر خواص غشاهای شبکه ترکیبی بهره گرفته شد. نتایج حاصل از DSC نشان دهنده افزایش دمای انتقال شیشه ای (Tg) غشاها به ازای ازدیا...
The presence of bisphenol A (BPA) in wastewater, its toxicity and the hardness for complete degradation constitutes a serious environmental problem scientific challenge. enzyme laccase is an oxidoreductase capable oxidizing phenolic compounds, being one most efficient biocatalysts BPA removal. immobilization laccases to lead solid essential their applications as it allows stabilization easy rec...
The photocatalytic reduction of Cr(VI) is investigated over iron(III)-based metal-organic frameworks (MOFs) structured as MIL-88B. It is found that MIL-88B (Fe) MOFs, containing Fe3-μ3-oxo clusters, can be used as photocatalyst for the reduction of Cr(VI) under visible light irradiation, which is due to the direct excitation of Fe3-μ3-oxo clusters. The amine-functionalized MIL-88B (Fe) MOFs (de...
The alarming increase in pesticide residues poses a major threat to aquatic and natural habitats. Therefore, it has become essential design extremely operationally economically advantageous systems for the removal of carbofuran pesticides from wastewater. Here, an aluminum-based metal-organic framework (MOF), MIL-53-NH2, its modified forms, MIL-53-NH-ph, MIL-53-NH-ph-Fe, MIL-53-NH-ph-Zn, MIL-53...
