The electrodeposition of polypyrrole films from aqueous surfactant solution through a two‐dimensional polystyrene template onto indium‐tin oxide substrate has been investigated. The polymer grows in the interstitial spaces of the self‐assembled polystyrene spheres, which were subsequently removed by dissolution in toluene. The new obtained surface was characterized by scanning electron microscopy and atomic force microscopy. Platinum nanoparticles were deposited onto the nanostructured polypyrrole electrode and used as a catalyst for the oxidation of ethanol for direct ethanol fuel cells. © 2014 Wiley Periodicals, Inc.
