Graphical Abstract

Über die Brücke: Mit zeitaufgelöster oberflächenverstärkter IR-Spektroskopie (SEIRAS) in Kombination mit Chronoamperometrie wird nachgewiesen, dass Ameisensäure über brückenartig gebundenes adsorbiertes Formiat oxidiert wird und dass die Formiatzersetzung der geschwindigkeitsbestimmende Schritt ihrer Elektrooxidation an Pt zu CO2 ist. Der Beitrag der direkten Oxidation von Ameisensäure über schwach adsorbiertes HCOOH ist bestenfalls vernachlässigbar.
