文摘

In this work, fullerene was modified by platinum, ruthenium, tin and tungsten nanoparticles. The material was characterized by XRD, ICP-OES and TEM micrograph. The average nanoparticle size on fullerene was 5-8 nm. The application of this material was investigated as a catalyst for methanol oxidation in direct methanol fuel cell. A glassy carbon electrode was modified by Pt/Ru/Sn/W fullerene and electrocatalytic activity of the electrode toward methanol oxidation in basic medium has been demonstrated and investigated using cyclic voltammetry. The catalyst showed good reactivity for methanol oxidation.
