Polypyrrole film architectures influence on platinum nanoparticles efficiency in ethanol electrooxidation

Abstract

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.

Synthesis of a hole‐containing polypyrrole film modified by copper cementation

“…Polypyrrole is one of the conducting polymers which has been extensively investigated due to its physicochemical stability, high conductivity, easy processability, and relatively low cost . The incorporation of metal particles into the polymeric matrix has received considerable attention due to the potential applications of these composites in catalytic materials, microelectronic devices, chemical sensors, and protection against corrosion . Ag, Cu, and Au are among the metals used to modify polymers.…”
