Abstract

A bridge too far: Time-resolved surface-enhanced infrared spectroscopy (SEIRAS) coupled with chronoamperometry shows that formic acid is oxidized via bridge-bonded adsorbed formate, and that formate decomposition is the rate-determining step in the electrooxidation of formic acid to CO2 on Pt. The contribution of direct oxidation of formic acid via weakly adsorbed HCOOH is negligible at best.
