Novel single step electrochemical route to gamma-MnO2 nanoparticle-coated polyaniline nanofibers: Thermal stability and formic acid oxidation on the resulting nanocomposites
gamma-MnO2 nanoparticles-coated polyaniline (PANI) nanofibers on carbon electrode were prepared by potentiodynamic electrochemical deposition of PANI and MnO2 from a single pot. Higher thermal stability of the resulting nanocomposites and their activity for formic acid oxidation permits the realization of a platinum-free anode for formic acid fuel cells.
