Babaluo Nanostructure Materials Research Center (NMRC), Sahand University of Technology Research Center of Polymeric Materials, Sahand University of Technology, B. Bayati Research Center of Polymeric Materials, Sahand University of Technology Journal Article 2007 04 08 Due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple and low cost method is very important. In this work, Pd nanoparticles were synthesized with narrow size distribution by loading metal salt (Pd(OAc)2 ) into the polymeric matrix (PEG) as reducing agent and stabilizer. Also, the effect of metal salt concentration and PEG molecular weight on the conversion of Pd 2+ to nano Pd 0 and synthesized palladium nanoparticles morphology were investigated by UV-vis spectroscopy, XRD and TEM. The UV results confirmed the significant effect of PEG molecular weight on the reduction reactivity of polymeric matrix. Also, TEM and XRD results revealed that metal salt concentration has significant effect on the synthesized Pd nanoparticles size. https://www.ijnnonline.net/article_4003_3ce83f544dbe69bb4fb19211fc442c2f.pdf
