Abstract

Pt-Ru@CP-MWNT catalysts were prepared by radiolytic deposition of Pt-Ru nanoparticles on conduction polymer (CP) coated multi walled carbon nanotubes (MWNTs) surfce. Three different types of conducting polymers; polypyrrole(PPy), polyaniline(PANI), and polythiophene (PTh), were coated on the MWNTs surface by in situ polymerization. Then Pt-Ru nanoparticles were deposited onto CP-MWNTs composite by the reduction of metal ions using gamma-irradiation to obtain Pt-Ru@CP-MWNT catalysts. The size, morphology and composition of Pt-Ru@CP-MWNT catalysts were characterized by SEM, TEM and elemental analysis. The catalytic efficiency of Pt-Ru@CP-MWNT catalyst was examined for CO stripping. Pt-Ru@PPy-MWNT and Pt-Ru@PANI-MWNT electrodes show enhanced activity for electrooxidation of CO and methanol over Pt-Ru@PTh-MWNT catalyst.
