Organic semiconductors are promising materials for the photocatalytic treatment of pollutants and organic synthesis. Herein, MIL-53(Fe)@perylene diimide (PDI) heterojunctions were constructed by ultrasonic assembly using PDI as co-catalyst, supramolecular material was uniformly distributed on surfaces MIL-53(Fe). The most effective M53@PDI-20 achieved 72.7% photodegradation rhodamine B (10 mg/L...
asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...
در این تحقیق به بررسی اثر ذرات mil-53، بر خواص غشای ماتریمید در جداسازی دی¬اکسیدکربن/متان، پرداخته شده¬است. از mil-53 که یک چارچوب آلی فلزی با حفراتی با ساختار ویژه بوده و گزینش¬پذیری قابل توجهی نسبت به گاز دی-اکسیدکربن دارد، به عنوان افزودنی استفاده شده¬است. به منظور بررسی ساختار غشاهای شبکه آمیخته با ترکیب درصدهای مختلف از ذرات mil-53، غشاهای مورد نظر به دو روش متقارن و نامتقارن ساخته شدند. س...
MOF-derived carbon-based materials have attracted widespread attention due to their relatively large surface area, morphology, and stability in water. Considering these advantages, present themselves as excellent adsorbents. In this work, a novel method was designed for the fabrication of nano zero-valent-iron (nZVI) carbon composite. The utilization zinc oxide nanorods (ZnONRs) role sacrificia...
A mixed cation MIL-53(Cr-Fe) MOF has been obtained by direct synthesis. Multiple experimental techniques have demonstrated the presence of a genuine mixed phase, leading to a breathing behaviour different from either of the single cation analogues.
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...
MIL-53(Fe) was prepared and modified with benzoic acid to prepare MIL-53(Fe)-BA additive, which used improve the catalytic oxidation rate of sulfite, prevent scaling desulfurization tower, efficiency during wet flue gas (WFGD) process power plants. exhibits abundant Lewis sites because appearance coordination unsaturated Fe atoms. Due excellent sorption capacity, Ca(OH)2 as main SO2 desulfurize...
Heterojunction catalysts have drawn increasing interest for the visible light-driven Fenton reaction and bring tremendous opportunities environmental remediation. Herein, a BiOI/MIL-53(Fe) Z-scheme heterojunction (named BMFe) was synthesized first time via facile strategy. Compared with pristine BiOI MIL-53(Fe) catalysts, two-dimensional/three-dimensional (2D/3D) catalyst manifested remarkable ...
