中文摘要	au-pt core-shell nanoparticles were prepared on glass surface by a seed growth method. gold nanoparticles were used as seeds and ascorbic acid-h2ptcl6 solutions as growth solutions to deposit pt shell on the surface of gold nanoparticles. these core-shell nanoparticles and their growth process were examined by uv-vis spectroscopy, x-ray photoelectron spectroscopy, atomic force microscopy and field-emission environmental scanning electron microscopy and the results indicated that the deposition speed was fast and nanoparticles with obvious core-shell structure could be obtained after 2 min. moreover, this seed growth method for preparation of the core-shell nanoparticles is simple and convenient compared with other seed growth methods with nh4oh as a mild reductant. in addition, electrochemical experiments indicated that these au-pt core-shell nanoparticles had similar electrochemical properties to those of the bulk pt electrode.
