Cover Picture: Oxidation of Formic Acid and Carbon Monoxide on Gold Electrodes Studied by Surface-Enhanced Raman Spectroscopy and DFT (ChemPhysChem 12/2005)
The cover picture shows an artistic impression of a formate anion adsorbed on a gold electrode, as probed by surface-enhanced Raman spectroscopy (SERS). By a combination of SERS and density functional theory calculations, the surface-bonded formate anion is shown to be the key intermediate in formic acid oxidation on gold electrodes. Formic acid oxidation activity on gold is also compared to the remarkable electro-oxidation properties of gold towards carbon monoxide. Find out more in the Article by Beltramo et al. on p. 2597.
