【 摘 要 】

We report Pt hexapod nanoparticles with 6.4 ~ 9.7 nm in size by a polyol process in the presence of PVP as a stabilizer and additive as a kinetic controller. The structure and morphology of Pt nanostructures are confirmed by field-emission transmission electron microscopy. The morphological control over platinum nanoparticles is achieved by varying the amount of seeds in the polyol process, where platinum precursor is reduced by ethylene glycol to form Pt nanoparticle at 150 oC. As volume ratio between precursor-solution and seed-solution is increased from 10 to 50, the shape of Pt nanostructures is evolved from small seeds to tripod and hexapod. In addition, the size-controlled platinum hexapod nanostructures are successfully obtained using seeding method.
