Ultrafine ruthenium nanoparticles (NPs) within the mesopores of the SBA-15 have been successfully prepared by using a "double solvents" method, in which n-hexane is used as a hydrophobic solvent and RuCl3 aqueous solution is used as a hydrophilic solvent. After the impregnation and reduction processes, the samples were characterized by XRD, TEM, EDX, XPS, N2 adsorption-desorption, and ICP techn...

A family of heterogeneous catalysts has been prepared by employing different strategies: firstly by direct reaction or grafting of titanium, zinc, aluminium and magnesium precursors with dehydrated SBA-15 and secondly by reaction of the metallic derivatives with a hybrid SBA-15 mesoporous material, which possesses a new covalently bonded linker based on an amino alcohol chelate ligand. These ma...

grinding (solvent-free) method was used as a superior technique to prepare mesoporous photocatalysts of zno, zns, zno / zns, cdo, cds and cdo / cds-sba-15. in this technique, the nitrate, acetate and chloride salts of zinc and/or cadmium were grinded with as-synthesized sba-15 as a mesoporous material. the controllable sulfurationis was used to prepare zns, zno/zns, cds and cdo/cds-sba-15 at te...

SBA-15 was utilized as mesoporous support for the dispersion of vanadium phosphate (VPO) compounds. Loading of SBA-15 with VPO compounds was found to be accompanied by decreasing (29)Si MAS NMR signals of Q(2) (Si(2Si,2OH)) and Q(3) (Si(3Si,1OH)) silicon species, which indicates coverage of the mesoporous support by the guest compounds. The (51)V MAS NNR spectra of the activated VPO/SBA-15 cata...

Magnolol (MG) is a small-molecule neolignan polyphenolic compound isolated from the genus Magnolia. The anti-inflammatory, anti-oxidative, anti-diabetic, anti-tumorgenic, anti-neurodegenerative, anti-depressant and anti-microbial properties of MG are well documented in recent literature. These fascinating multiple biological activities of MG encourage research about the development of new deliv...

Grinding (solvent-free) method was used as a superior technique to prepare mesoporous photocatalysts of ZnO, ZnS, ZnO / ZnS, CdO, CdS and CdO / CdS-SBA-15. In this technique, the nitrate, acetate and chloride salts of zinc and/or cadmium were grinded with as-synthesized SBA-15 as a mesoporous material. The controllable sulfurationis was used to prepare ZnS, ZnO/ZnS, CdS and CdO/CdS-SBA-15 a...

The stable silica sieve-based HBeta-SBA-15 catalyst-carrier was successfully prepared by a hydrothermal synthesis method, and then Ni2P/HBeta-SBA-15 new hydrodeoxygenation catalyst loaded the equal volume impregnation method. It characterized X-ray diffraction (XRD), N2 adsorption-desorption, scanning electron microscopy (SEM), transmission (TEM), pyrolysis-infrared (Py-IR) methods. results sho...

A carrier system based on nanoporous silica (SBA-15) with magnetic nanoparticles of CoFe2O4 was synthesized via the impregnation of cobalt salt, iron salt and citric acid with as-synthesized SBA-15. The obtained samples were characterized by small angle X-ray scattering (SAXS), N2 adsorption/desorption, scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and ultraviolet (UV)...

Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...
