Platinum-Ruthenium-Multiwalled Carbon Nanotube-Nafion Nanocomposite for Methanol Electrooxidation


Article Preview

This work presented the electrochemical reduction of platinum (Pt) and ruthenium (Ru) nanoparticles within multiwalled carbon nanotube-Nafion (MWCNT-Nafion) composite for electrochemical oxidation of methanol. The structure of the resulting Pt-Ru-MWCNT-Nafion nanocomposite was characterized by scanning electron microscopy, transmission electron microscopy, and energy dispersive X-ray spectroscopy. Electrochemical properties of Pt-Ru-MWCNT-Nafion nanocomposite were investigated by cyclic voltammetry in a 2 M CH3OH + 1 M H2SO4 aqueous solutions. The Pt-Ru-MWCNT-Nafion nanocomposite modified electrode had high electrocatalytic activity and performance toward the methanol electrooxidation as compared with Pt-MWCNT-Nafion nanocomposite modified electrode.
