Deep Extractive Oxidative Desulfurization of Model Oil by Magnetically Recoverable Polyoxometalate-Based Nano Catalyst
Dibenzothiophene (DBT), benzothiophene (BT) and thiophene (T) were catalytically oxidized to their corresponding sulfone products by H2O2 in the presence of magnetically recoverable polyoxometalate-based nano catalyst. Different extracting solvents including ethanol, acetonitrile, and dimethylformamide were tested. The best results were obtained by ethanol extraction. The oxidative desulfurizat...

15 صفحه اولFe3O4/FDU-12: A highly efficient and magnetically separable nano-catalyst for oxidation of alcohols
A series of Fe3O4 supported on mesoporous FDU-12 silica systems were prepared by the hydrothermal conditions. The surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like FTIR, XRD, N2 adsorption–desorption and TEM. XRD and adsorption–desorption analysis shows that the mesostructure of FDU silica remains intact after Fe3O4 modifications, wh...

متن کاملAliphatic alcohols oxidation with Hydrogen Peroxide in water catalyzed by supported Phosphotungstic acid (PTA) on Silica coated MgAl2O4 nanoparticles as a recoverable catalyst
In this paper, a novel catalyst (MgAl2O4@SiO2-PTA) was proposed for the green oxidation of aliphatic alcohols. The resultant composite was characterized by different techniques, such as X-ray diffraction (XRD), SEM, FT-IR, EDX and Brunauer-Emmett-Teller (BET) surface area analysis. The prepared nanocomposite was used as a catalyst for oxidation of aliphatic alco...
