| 摘要 |
This invention comprises a method of preparing stabilized core/shell structured nanoparticles comprising core material being at least one member a first metal group, said first metal group consisting of Pd, Au, NiPd or CoPd and shell material comprising Pt and at least one member of a second metal group, said second metal group consisting of Fe, Ni, Cu comprising (a) preparing a monodispersion of said core material wherein said monodispersion is in a size range of from about 3nm to about about 20nm; (b) forming core/shell structured nanoparticles by adding shell material to monodispersion; and,(c) stabilizing said structured nanoparticles, as well as stabilized core/shell structured nanoparticles per se. Further included is a method of preparing NiPd and CoPd nanoparticles. |
