摘要：

(Graph Presented) Revised model: Current oscillations in the electrooxidation of formic acid at a fixed potential can be observed by time-resolved surface-enhanced infrared absorption spectroscopy (see picture). Real-time probing of the reaction dynamics on the electrode surface provides new insight into the oscillations that are not accessible by conventional techniques. The reaction mechanism involves adsorbed formate as a reactive intermediate. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
