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 CO 2 on Pt. The contribution of direct oxidation of formic acid via weakly adsorbed HCOOH is negligible at best.
