Platinum nanoparticles (Pt NPs) with a mean diameter of 2.7 ± 0.8 nm were successfully deposited on C60 fullerene nanowhiskers (C60FNWs) by coaxial arc plasma deposition (CAPD). No correlation was observed between the face-centred cubic (fcc) lattice constant and the diameter of the deposited Pt NPs, while the mean fcc lattice constant of the Pt NPs on C60FNWs was less than that of bulk Pt and significantly different from that of the Pt NPs deposited on graphite particles. The Pt NPs deposited on graphite particles showed larger lattice strains than the Pt NPs deposited on C60FNWs. These results suggest that the strained structure of Pt NPs deposited by CAPD changes depending on the surface energy of the carbon substrate.
