Oxidation and adsorption of Co at Pt−Au-SPE electrodes

  • Published:
Wuhan University Journal of Natural Sciences

Abstract

Pt−Au-SPE electrodes made by the successive chemical deposition of Au and Pt on Nafion membranes were tested and compared with the single metal-SPE electrodes for surface oxidation, CO adsorption and oxidation. Part of the surface of the binary metal electrodes behaves differently from either Au or Pt single metal-SPE electrode for COads oxidation, revealing surface modulation effects in the binary metal electrode. However, these mudulated surfaces have no appreciable contribution to the electrode activity for CO oxidation. The electrode activity for CO oxidation is mainly governed by the total Pt surface area of the binary electrodes. The predeposited Au was found to be favorable for higher dispersion of the successively deposited Pt.
