Influence of a Surfactant and Reducing Agent on Preparation of Palladium

Abstract

We investigated the influence of a surfactant and reducing agent on the preparation of palladium nanoparticles, characterizing the prepared palladium nanoparticles by Transmission Electron Microscopy (TEM), and X-ray diffractometer (XRD). Colloidal palladium nanoparticles are prepared using PdCl2 as a precursor and polyvinylpyrrolidone (PVP) as a surfactant. In addition, hydrogen and sodium borohydride are used as reducing agents are used to characterize the prepared palladium nanoparticles. The concentrations of a precursor, a surfactant and its molecular weight affect the size of palladium nanoparticles, while the reducing agents influence the morphologies and structures of palladium nanoparticles.
