Synthesis of Graphene with Noble Metals Nanoparticles on its Surface

Graphene sheets can be considered as a promising a support material for the catalytic nanoparticles. Here, we present a new approach for the preparation of graphene with noble metals nanoparticle on its surface using supercritical propanol - 2 as a reducing agent for nanocomposites graphene oxide- Pd or Pt nanoparticles. The prepared nanocomposites were characterized by X-ray diffraction analyses (XRD) and transmission electronic microscope (TEM). XRD reveals the face-centered cubic structure of Pd and Pt in the nanocomposites, TEM images show the good spatial distribution of metal nanoparticles on layered graphene sheets.
