Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...

copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [cu3(btc)2] (1) and [cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°c. it has also been found that the reaction temperature pla...

metal-organic frameworks (mofs) represent a new class of highly porous materials. on this regard,  two nano porous metal-organic frameworks of [zn2(1,4-bdc)2(h2o)2∙(dmf)2]n (1) and [zn2(1,4-bdc)2(dabco)]·4dmf·1⁄2h2o (2), (1,4-bdc = benzene-1,4-dicarboxylate, dabco = 1,4-diazabicyclo[2.2.2]octane and dmf = n,n-dimethylformamide) were synthesized and characterized. they were used for preparation ...

The use of waste materials as organic amendments in soil remediation can affect metal solubility; this interaction will vary with the characteristics of the organic matter that is added to the soil. A pot experiment was carried out in a calcareous, metal-polluted soil, using Beta maritima L. as an indicator species for the treatment effects on metal solubility. The treatments were: fresh solid ...

Metal-Organic Framework (MOFs) are new crystalline materials which because of having propertiessuch as high porosity, optical and electrical properties, etc., have been considered in areas such as gasstorage, catalysis, pollutants removal and so on. Therefore, in order to develop these compounds andtheir use in this study, in this work, Zn-HKUST-1 metal-organic framework was synthesized by fast...

The photoreductive dissolution of Mn(IV) oxide minerals in sunlit aquatic environments couples the Mn cycle to the oxidation of organic matter and fate of trace elements associated with Mn oxides, but the intrinsic rate and mechanism of mineral dissolution in the absence of organic electron donors is unknown. We investigated the photoreduction of δ-MnO2 nanosheets at pH 6.5 with Na or Ca as the...

Although the magnetoelectric effects - the mutual control of electric polarization by magnetic fields and magnetism by electric fields, have been intensively studied in a large number of inorganic compounds and heterostructures, they have been rarely observed in organic materials. Here we demonstrate magnetoelectric coupling in a metal-organic framework [(CH3)2NH2]Mn(HCOO)3 which exhibits an or...

Use of the tritopic bridging ligand 1,3,5-benzenetristetrazolate (BTT3-) enables formation of [Mn(DMF)6]3[(Mn4Cl)3(BTT)8(H2O)12]2.42DMF.11H2O.20CH3OH, featuring a porous metal-organic framework with a previously unknown cubic topology. Crystals of the compound remain intact upon desolvation and show a total H2 uptake of 6.9 wt % at 77 K and 90 bar, which at 60 g H2/L provides a storage density ...

zinc (ⅱ) tricarboxylate (zn-btc) with metal-organic framework (mof) has been synthesized for the first time under solvothermal conditions and has been tested as an adsorbent for methane and carbon dioxide at standard temperature and pressure. the adsorbent was characterized by means of x-ray diffraction(xrd), brunauer-emmet-teller (bet), fourier transform infrared (ft-ir) and scanning electron ...
