Abstract

Abstract: Conducting polymer nanostructures having anisotropic morphology and rich redox properties, employed as support for palladium metal catalysts for electrooxidation of ethanol. Polypyrrole nanofibers have been first synthesized using soft oxidative templates and consequently, a unique Pd-branched structure was nucleated on the polymer surface by photo-reduction method.

This work demonstrates a new and facile approach for the synthesis of electrocatalysts with both the enhanced activity and durability for fuel cell applications.
