This article has been recently published in the journal Carbon, and here, we report the synthesis C60 nanorods (NRs) and its subsequent decoration with palladium nanoparticles. We modified the NR surface via in situ photochemical transformation in the liquid state, in order to obtain highly stable NRs that retain their crystalline structure during the decoration process. We also show that the photo-transformed C60 NRs exhibit highly advantageous properties for ethanol oxidation based on both a better crystallinity and a higher bulk conductivity.

Our method thus opens up for the synthesis of highly crystalline nanocomposite hybrids comprising Pd nanoparticles and C60 NRs. Bys measuring the electron mobility of different C60 NRs, we relate both the effect of electron mobility and crystallinity to the final electrocatalytic performance of the synthesized hybrid structures. We show that the photo-transformed C60 NRs exhibit highly advantageous properties for ethanol oxidation based on both a better crystallinity and a higher bulk conductivity. These findings give important information in the search for efficient catalyst support.
