Five current peaks in voltammograms for oxidations of formic acid, formaldehyde and methanol on platinum
Article Abstract:
A study is conducted to relate the peaks present in the voltammograms among the three substances, namely formic acid, formaldehyde and methanol and to examine the conditions to obtain distinct peaks in the voltammogram. Results strongly support the idea that the electrochemical oxidation mechanisms for the three substances have the same dominating elementary reaction steps, which induce oscillation phenomena, although different reaction and adsorption rate constants.

Potential oscillations in galvanostatic electrooxidation of formic acid on platinum: A mathematical modeling and simulation
Article Abstract:
A mathematical model that simulates potential oscillations in formic acid oxidation was proposed on the basis of surface-enhanced infrared absorption spectroscopy SEIRAS. The model was constructed within the framework of the dual-path mechanism and a direct path via a reactive intermediate and an indirect path via strongly bonded CO formed by dehydration of formic acid.

Potential oscillations in galvanostatic electrooxidation of formic acid on platinum: A time-resolved surface-enhanced infrared study
Article Abstract:
Potential oscillations that occur during galvanostatic formic acid oxidation on a Pt electrode are investigated by time-resolved surface-enhanced infrared absorption spectroscopy (SEIRAS). Temporal potential oscillations allowed carbon monoxide (CO) and formate to adsorb on the surface and change their coverages synchronously.
