Dual Pd and CuFe2O4 nanoparticles encapsulated in a core/shell silica microsphere for selective hydrogenation of arylacetylenes.
A dual catalyst containing Pd and CuFe(2)O(4) nanoparticles in a silica shell exhibits >98% conversion of arylacetylenes to related styrenes with selectivity greater than 98%, which are better than those obtained using a commercial Lindlar catalyst. The excellent synergy was likely a result of the proximal interaction between Pd and CuFe(2)O(4) nanoparticles.
متن کاملRole of low-coordinated surface sites in olefin hydrogenation: a molecular beam study on Pd nanoparticles and Pd(111).
Hydrogenation of unsaturated hydrocarbon compounds catalyzed by transition metals is traditionally believed to be a structure-insensitive reaction. However, recent progress in understanding the microscopic details of this process challenges the universality of this common belief. Recently, several examples of catalytic systems were described in the literature where hydrogenation of the olefinic...
متن کاملFunctionalized porous silica&maghemite core-shell nanoparticles for applications in medicine: design, synthesis, and immunotoxicity
AIM To determine cytotoxicity and effect of silica-coated magnetic nanoparticles (MNPs) on immune response, in particular lymphocyte proliferative activity, phagocytic activity, and leukocyte respiratory burst and in vitro production of interleukin-6 (IL-6) and 8 (IL-8), interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), and granulocyte macrophage colony stimulating factor (GM-CSF)....
متن کاملAqueous electrolytes confined within functionalized silica nanopores.
Molecular dynamics simulations have been carried out to investigate structural and dynamical characteristics of NaCl aqueous solutions confined within silica nanopores in contact with a "bulk-like" reservoir. Two types of pores, with diameters intermediate between 20 Å and 37.5 Å, were investigated: The first one corresponded to hydrophobic cavities, in which the prevailing wall-solution intera...
متن کاملCisplatin-functionalized silica nanoparticles for cancer chemotherapy
Cisplatin is used to treat a variety of tumors, but dose-limiting toxicities or intrinsic and acquired resistance limit its application in many types of cancer including breast. Cisplatin was attached to silica nanoparticles using aminopropyltriethoxy silane as a linker molecule and characterized in terms of size, shape, as well as the dissolution of cisplatin from the silica surface. The prima...
