چکیده
Abstract A novel CuWO 4 /SiO 2 heterojunction catalyst was successfully synthesized using a new sulfonamide derivative. The physical characteristics of the prepared samples were investigated by TGA, XRD, FTIR, SEM, UV, PL, and XPS. catalysts applied as nano photocatalyst for photooxidative desulfurization dibenzothiophene under visible light hydrogen peroxide an oxidant. photocatalytic oxidative performances investigated. Various factors reaction time, concentration, dose, oxidizing agent dose also studied. has high activity in removal DBT mild conditions. Results showed that exhibited considerably higher than neat support SiO . Such improved is mainly attributed to efficient separation photogenerated electron–hole pairs on heterojunction. Moreover, synergistic effects this oxidation green oxidant played essential role desulfurization. pseudo-first-order can reach 98.6% after 70 min 97.2% four cycles. Graphical

Oxidative desulfurization of dibenzothiophene with molecular oxygen using emulsion catalysis.
Dibenzothiophene (DBT) is oxidized to the corresponding sulfoxide and sulfone in an emulsion system (W/O) composed of polyoxometalate anion [C(18)H(37)N(CH(3))3](5)[PV(2)Mo(10)O(40)] as both the surfactant and catalyst, using molecular oxygen as the oxidant and aldehyde as the sacrificial agent under mild conditions.
متن کاملA Soft and Efficient Approach for Removal of Template from Mesoporous Silica using Benzene Sulfonamide
In this contribution, an effective and soft method for removal of template from nanochannels of mesoporous silica (MCM-41) is proposed. This method is based on chemically-modified solvent extraction which enhanced by means of an auxiliary organic compound, i.e. benzene sulfonamide. Template removal was performed in soft condition, i.e. in the presence of diluted sulfuric acid and at ambient tem...

Spherical mesoporous silica MCM-41 was synthesized for adsorptive removal of sulfur compounds from fossil fuels using 1mM solution of dibenzothiophene (DBT) in dodecane as model oil. The prepared silica adsorbent has been characterized by nitrogen adsorption-desorption analysis as well as Small Angle X-ray Scattering (SAXS), and transmission and Scanning Electron Microscopy (SEM) methods. R...
