英文摘要Silver sulfide hollow sphere-silver nanoparticle heterostructures were prepared by the simultaneous cation exchange and oxidation-reduction reactions of Cu2S hollow spheres with Ag+ ions in aqueous solution. The obtained Ag2S-Ag hybrid hollow spheres consisted of Ag2S hollow spheres about 600 nm in diameter and 20-30 nm in thickness with a single Ag nanoparticle attached to the outer surface of each Ag2S hollow sphere. The products were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and energy dispersive X-ray spectroscopy (EDS). When CuS hollow spheres were used as the reactive template instead of Cu2S hollow spheres, Ag2S hollow spheres were the predominant product under similar reaction conditions, indicating that the Cu(I) in the Cu2S hollow spheres served as a reductant for reducing Ag ions to metallic Ag, and hence played a key role in the formation of the Ag2S-Ag hybrid hollow spheres. Furthermore, secondary deposition of Ag on the Ag2S-Ag hybrid hollow spheres resulted in the formation of larger Ag2S-Ag hybrid hollow spheres consisting of Ag2S hollow spheres with around a half of the surface coated by a Ag film.
