摘　　要：以甲基异丁酮为溶剂,在少量乙二醇和KOH存在下,乙酸钯经微波辐照加热60 s可以得到溶剂稳定的海胆状Pd纳米颗粒自组装体,颗粒平均粒径较小,大小均匀,分散性好.产物用透射电子显微镜(TEM)、X-射线光电子能谱(XPS)和X-射线粉末衍射(XRD)进行了表征.Solvent-stabilized urchin-like self-assemblies of Pd nanoparticles with a small average diameter,uniform size and well dispersed were obtained by thermal decomposition of palladium acetate with methyl isobutyl ketone as a solvent in the presence of a small amount of ethylene glycol and KOH under microwave irradiation for 60 sec.The as-prepared Pd nanoparticle self-assemblies were characterized by transmission electron microscopy,X-ray powder diffraction and X-ray photoelectron spectroscopy.
