| Abstract: Monodispersed nano-Pd particles were prepared by sonochemical reduction of a 1∶12 molar mixture of palladium(Ⅱ) chloride(PdCl2), and sodium dodecyl sulfate (SDS) in double deionized aqueous solution. The reducing substance was characterized by transmission electron microscopy (TEM) with selected area electron diffraction (SAED), Fourier transform infrared (FTIR) and X-ray photo electron specstropy analysis (XPS). The results show that the reduction of Pd(Ⅱ) to metallic Pd is achieved and that the obtained suspensions have a long life period. The Pd nanoparticles are highly dispersed and uniform in size (in the range of 1～10 nm). The protective effect of SDS for Pd nanoparticles was investigated and the results indicate that there are interactions between Pd and SDS. |
