説明

In this paper, poly (vinylpyrrolidone) (PVP) protected Pt and Pt-Pd nanoparticles were synthesized by the reductions of H_2PtCl_6 and Na_2PdCl_4 in ethylene glycol (EG) using AgNO_3 as a structure-controlling agent. Transmission electron microscopy (TEM) and high resolution (HR) TEM were employed to study the morphology and size of Pt and Pt-Pd nanoparticles. The results showed that the size and morphology of Pt nanoparticle was precisely controlled by addition of AgNO_3. Accordingly, only under the selection of the appropriate chemicals and experimental conditions, Pt-Pd nanoparticles with their core-shell morphology were precisely controlled.
