摘　　要：在吡啶 水体系中用KBH4还原H2PtCl6首次制得了贵金属Pt纳米粒子且纳米Pt体系不受空气的影响可以较长时间的存在,并通过透射电镜(TEM)、低能电子衍射和紫外漫反射(UV Vis)对其进行了表征.Pt纳米粒子的平均粒径在2.0～3.0nm,该体系同时也可以制备Ru、Pd等纳米粒子.Pyridine-protected platinum nanoparticles were synthesized by 'one-potreaction' method. The whole process involved KBH_4 as the reductant at room temperature and the time of reaction also could be shorten within 2h. Pyridine-protected platinum nanoparticles is not destroyed by air. Transmission electron microscopy shows that the mean Pt-nanoparticle size ranges between 2.0～3.0 nm. An electronic diffractionnation demonstrated the present of zerovalent platium. And Ru and Pd nanoparticles were prepared by the same method.
