Title:"Carbon Dioxide Activation and Reaction Induced by Electron-Transfer at an Oxide-Metal Interface"Abstract:A model system has been created to shuttle electrons through a metal-insulator-metal (MIM) structure in order to induce the formation of a CO2 anion radical from adsorbed gas phase carbon dioxide that consecutively reacts to form an oxalate species. The process is completely reversible, and thus allows us study the involved elementary steps at the atomic level. The oxalate species at the MIM interface have been identified locally by scanning tunneling microscopy, chemically by infrared spectroscopy and their formation verified by density functional calculations.
