Mesoporous metal-organic frameworks Cr- and Fe-MIL-101 are highly efficient, true heterogeneous and recyclable catalysts for solvent-free selective oxidation of cyclohexane with molecular oxygen and/or tert-butyl hydroperoxide under mild conditions.
Hollow magnetic Fe3O4@NH2-MIL-101(Fe) derived from metal-organic frameworks are fabricated through a general facile strategy. The synthetic parameters are regulated to control the shape of the as-prepared samples. The concentration of phosphates decreased sharply from the initial 0.60 to 0.045 mg.L(-1) with the exposure time in 50 minutes. The correlation between the most significant parameters...
•A systemic assay package was developed to seek MOFs for biomedical applications•Fe-based exhibited superb features that are suitable cutaneous treatment•The relationship between MOFs’ structure and their performance in-depth analyzed•This study provides guidance design materials treatment Nowadays, has been widely applied in the cosmetic pharmaceutical fields. However, traditional used often s...
This study investigates the role of reagent ratio, solvent composition and temperature on solvothermal synthesis MOF-235(Fe) MIL-101(Fe).
The amino group in the MOF NH2-MIL-101(Cr) was post-synthetically converted into urea-groups partially using either ethyl isocyanatoacetate, furfuryl isocyanate, p-toluenesulfonyl isocyanate or 3-(triethoxysilyl)propyl acetonitrile. derived four novel urea-MOFs exhibit expected lower BET surface areas and pore volumes than MIL-101(Cr) MOFs but p-toluenesulfonyl-urea-modified exhibits an outstan...
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...
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...
طراحی کاتالیست های ناهمگن فعال انتخابی و قابل بازیابی، هدف چالش برانگیز در واکنش های اکسایشی کاتالیستی است. اخیراً دسته ی جدیدی از کاتالیست های ناهمگن بر پایه ی اسکلت های فلز- آلی (دسته ی جدیدی از مواد متخلخل هیبریدی فلز- آلی با ساختار شبکه ای نامتناهی) به عنوان کاتالیست های ناهمگن اکسایشی گزارش شده اند. در این تحقیق، سه دسته کاتالیست نانومتخلخل و ناهمگن بر پایه اسکلت های فلز- آلی به روش های حلا...
Cu3(BTC)2 is an efficient and reusable heterogeneous catalyst for the dehydrogenative coupling of silanes with alcohols. Activity data and CO adsorption suggest that Cu(II) and in situ generated Cu(I) are the active species. Other MOFs such as Fe(BTC), MIL-101(Cr) and UiO-66(Zr) are unable to promote this cross-coupling.
Introduction: Noninvasive magnetic resonance imaging (MRI) and targeted drug delivery systems, usually referred to as theranostic agents, are being developed to enable detection, site-specific treatment, and long-term monitoring. Materials and Methods: To elucidate the effects of coating on cellular uptake and biodistribution of n...
