Abstract

The aim of this work was to prepare a nanocomposite membrane based on platinum nanoparticles dispersed onto/inside of Nafion, by in situ reduction of platinum precursor. Two types of the reducing agent (sodium borohydride) concentrations have been used in order to investigate the influence over platinum nanoparticles size and distribution, performering complementary microstructural analysis, e.g. High Resolution-Transmission Electron Microscopy (HR-TEM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD)..

Keywords
