A novel composite electrode is fabricated through the electrodeposition of hydrous ruthenium oxide (RuO 2 ·xH 2 O) and platinum (Pt) particles into the matrix of polyaniline (PANI). Scanning electron microscopy reveals that RuO 2 ·xH 2 O and Pt particles are homogeneously distributed into the matrix of PANI. A comparison of the sizes of Pt and RuO 2 ·xH 2 O particles incorporated into the PANI film reveals that Pt particles are smaller in sizes as compared with the sizes of RuO 2 ·xH 2 O particles. The catalytic activity of composite electrodes was evaluated for the oxidation of methanol by using cyclic voltammetry and chronoamperometry. A relatively high catalytic current was noticed for the oxidation of methanol (2.37 mA/cm 2 ) at PANI‐Pt‐RuO 2 ·xH 2 O electrode (+0.6 V (V vs. Ag/AgCl) in comparison to oxidation current at PAN‐Pt (1.27 mA/cm 2 ) electrode.
