Potential oscillations and S-shaped polarization curve in the continuous electro-oxidation of CO on platinum single-crystal electrodes
Article Abstract:
The occurrence of an S-shaped polarization curve in a simple model for the continuous electrochemical oxidation of Co on a platinum electrode is discussed. The potentiodynamic and galvanodynamic experiments are carried out to test the predictions of this model and the evidence for the S-shaped polarization curve observed on all three low-index Pt surfaces in both perchloric and sulfuric acid solution is presented.

Pt-Ru and Pt-Ru-P/carbon nanocomposites: Synthesis, characterization and unexpected performance as direct methanol fuel cell (DMFC) anode catalysts
Article Abstract:
A study is conducted to construct six Pt-Ru/carbon nanocomposites with the help of five different Pt,Ru-bimetallic precursors as sources of metal. Direct methanol Fuel Cell (DMFC) data indicate that the presence of significant amounts of this ternary metal phosphide phase does not significantly reduce the performance of such catalysts, relative to the performance of commercial Pt-Ru/C electrocatalysts.
