| Abstract: | The photochemical synthesis of Pd nanoparticles was studied in dissoluble polymer system.Pd(II)-PEG-acetone solution was irradiated by UV-300nm light and the colloidal Pd nanoparticles obtained were characterized by TEM.The results show that Pd nanoparticles with fine dispersion are 1.8nm to5.7 nm in average diameter.The influence of PEG and acetone on the photochemical synthesis of Pd nanoparticles was investigated,respectively.Rapid photochemical reduction of Pd(II) ion and the mechanisms of stabilizing nanoparticles were discussed. |
