A three dimensional graphene/Pt catalyst fabricated by particle-constructing method and the catalytic activity for methanol oxidation

Wrapping PS microspheres with graphene sheets, attaching PtNPs on the resultant PS/rGO composite particles to prepare PS/rGO@PtNPs composite particles, and finally constructing 3D ordered rGO/PtNPs network structure through in-situ self-deposition of the ternary composites, which evidently increased the catalytic activity in methanol oxidation reaction than the close-packed rGO/PtNPs composite.191
