摘要：
Poly(N-vinyl-2-pyrolidone) protected Pt-core bimetallic Pt/Au-shell (Pt@Pt/Au) nanoparticles; were prepared by multi-step reduction of HAUC14 and H(2)PtCl6 alternately by hydrogen adsorbed on platinum atom. Transmission electronic microscopy (TEM) and x-ray diffraction (XRD) were used to characterize Pt@Pt/Au nanoparticles. The structure of the shell of the nanoparticles seems to be the Au-Pt solid solution.
