Electrochemical Oxidation of Dissolved Carbon Monoxide on Rotating Disk Electrodes and Micro-Electrodes

This work was to study the dissolved CO in solution phase by using rotating disk electrodes and the solution phase CO demonstrate the limiting currents dependence of rotating speeds. Gold and gold-platinum metals clusters are used in glassy carbon supported rotating disk electrode for electrochemical oxidation of the solution phase CO. Small metal clusters and Au-Pt alloy effects are observed in the measurements. The comparison of microelectrode and RDE study of solution phase CO electrochemical oxidation is confirmed the limiting currents dependence of the boundary layers concentrations.
