| 中文摘要 | A one-step facile synthesis is devised for preparation of well-dispersed Ag-Ni core-shell nanoparticles with uniform and intact shells. The process is performed by a reduction of silver nitrate and nickel nitrate with sodium borohydride in water-in-oil (W/O) microemulsions of water/polyoxyethylene (4) nonylphenol (OP-4) and polyoxyethylene (7) nonylphenol (OP-7)/n-heptane. Transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and UV-vis absorption are utilized to characterize the Ag-Ni core-shell nanoparticles. Furthermore, the effect of molar ratio of Ni(2+) to Ag(+) and dosage of Ni(2+) and Ag(+) on morphology of the core-shell nanostructure is also discussed in detail. The thickness of Ni layers on the surface of Ag nanoparticles could be controlled by the dosage of Ni(2+) and Ag(+). The Ag-Ni core-shell nanoparticles showed a high catalytic activity for degradation reaction of eosin Y. The product may also have many potential applications in optical, magnetic, biochemical, and biomedical fields. The synthetic method reported here suggests a very promising route for the preparation of bimetallic core-shell structures, which is a subject of intense interest. (C) 2010 Elsevier B.V.
