Abstract: Sonochemical reduction of Tetrachloropalladate (II) ions in water were carried out in the presence of an organic compound such as surfactant, water soluble polymer and alcohol, and the nanoparticles of Pd metal were synthesized. From the results of the XRD analysis and so on, it was found that carbon atoms were present on an interstitial sites of the Pd lattice. The mechanism of carbon insertion and the control of the number of carbon atoms in the Pd particles are discussed. Our experimental results suggest that the PdC phase may have been formed unintentionally by the conventional preparation methods of colloidal Pd metals, and indicate out that phase identification should be done carefully, considering the influence of the carbon uptake on the catalytic activity and/or surface chemistry of the particles.
