Abstract

original image

Modell revidiert: Mit zeitaufgelöster oberflächenverstärkter Infrarot-Absorptionsspektroskopie wurden Stromoszillationen in der Elektrooxidation von Ameisensäure bei konstantem Potential beobachtet (siehe Bild). Die Echtzeitanalyse der Reaktionsdynamik auf der Elektrodenoberfläche verschafft einen neuartigen Einblick in die Eigenschaften des Systems. Adsorbiertes Formiat ist als reaktives Intermediat am Reaktionsmechanismus beteiligt.
