Abstract:
Carbon is an indispensable material for the support of platinum (Pt) catalysts of polymer electrolyte fuel cells. Carbon nanotubes, graphene and graphite nanoplatelets have been recognized as promising new Pt carbon supports for their superior electrical, mechanical and surface properties. Recently, the coaxial arc plasma deposition (CAPD) method has attracted rising attention in preparing metal nanoparticles (NPs), since it is a simple dry process that can directly deposit metal NPs on substrates in vacuum, and the research to prepare Pt NPs on the above novel nanocarbons has been actively performed for the development of fuel cells. Using CAPD, we deposited Pt NPs on the various nanocarbon substrates, and the structure of the Pt NPs and nanocarbon substrates has been analyzed in atomic scale by use of high-resolution transmission electron microscopy (HRTEM) coupled with electron energy loss spectroscopy (EELS). Deposition of Pt NPs on fullerene nanowhiskers also has been conducted to demonstrate the strong applicability of CAPD even for such molecular crystals composed of fullerene molecules bonded via weak van der Waals bonding forces.
