Electrodesorption spectra of residues formed on electrochemically modified polycrystalline platinum from carbon dioxide, formic acid, methanol and ethylene glycol adsorption

Abstract

This preliminary report attempts to correlate the electrodesorption characteristics of adsorbed residues from those substances resulting on electrochemically modified polycrystalline platinum electrodes from acid and base solution, without interference of readsorption of the initial reactant from the electrolyte solution. This was accomplished by using the micro flux cell electrochemical technique. The modifications of polycrystalline platinum imply reconstruction and faceting processes yielding two different types of electrode surface topographies. These electrodes were recently tested in the electrooxidation of adsorbed CO in both acid and base electrolyte.
