摘　　要：Poly（N-vinyl-2-pyrrolidone）-protected Pt/Au bimetallic nanoparticles were obtained by reducing the mixture of HAuCl4 and H2PtCl6 with sodium borohydride.UV-vis spectra,transmission electronic microscopy and X-ray diffraction reveal that the prepared bimetallic nanoparticles are of alloy structure.Poly(N-vinyl-2-pyrrolidone)-protected Pt/Au bimetallic nanoparticles were obtained by reducing the mixture of HAuCl_4 and H_2PtCl_6 with sodium borohydride.UV-vis spectra,transmission electronic microscopy and X-ray diffraction reveal that the prepared bimetallic nanoparticles are of alloy structure.
