A facile preparation of Pt–Ru nanoparticles supported on polyaniline modified fullerene [60] for methanol oxidation.

The use of fullerene [60] (C 60) as carbon support material for the dispersion of catalysts, which provides new ways to develop the advanced electrocatalyst materials for its distorted structure. In this article, polyaniline (PANI)-modified C 60 (abbreviated as PANI-C 60) is introduced, and the platinum–ruthenium alloy nanoparticles are successfully supported on PANI-C 60. According to the transmission electron microscopy measurements, the average particle size of the as-prepared nanoparticles dispersed on PANI-C 60 is 2.4 nm. Electrochemical studies reveal that the Pt-Ru/PANI-C 60 nanocomposites show excellent electrocatalytic activity toward methanol oxidation, showing that the PANI-C 60 may be a better potential candidate to be used as the supports of catalyst for electrochemical oxidation.
