Abstract
⺠We have prepared Ag, Ni and AgNi NPs by derived seed-mediated growth method. ⺠The combined use of optical, structural and chemical characterization techniques allows to determine the presence of core-shell structures. ⺠The oxidation states of Ag and Ni at the outer layers of the NPs have been studied by XPS. ⺠Ag NPs are purely metallic with a fcc structure. ⺠Ni NPs are formed by Ni core@NiO + Ni(OH)2 shell structure. ⺠Ag core@NiO + Ni(OH)2 shell structure is determined for AgNi NPs, with oxidized silver atoms at the interface.
