Platinium-Ruthenium electrocatalyst as sensor electrode for methanol oxidation

Hybrid nanocomposites of binary Pt-Ru/Polyaniline were prepared by oxidative polymerization of aniline and formation Pt and Ru nanoparticles. The polymerization of aniline was carried out in the presence of Potassium hexa cyano Platinate (IV) and Ruthenium (III) nitrosyl nitrate as oxidizing agents. During the reaction aniline monomers undergo oxidation and form polyaniline (PANi) whereas the reduction of cations, result the fomiation of Pt and Ru nanoparticles. Nano-sized Pt and Ru particles were prepared by controlled reduction of precursors in micro emulsion medium, stabilized with the Sodium Dodecyl Sulfate. Micro emulsion solution acts as both emulsifier and dopant to obtain stable nanocomposite. Pt-Ru/PAn nanocomposites are characterized by cyclic voltammetry (CV). FT-IR spectroscopy and scarmine microelectronic microscopy (SEM).
