X-Ray Absorption Spectroscopy of Electrochemically Generated Species
Abstract
X-ray absorption fine structure (EXAFS) spectroscopy has been combined with electrochemistry to enable the measurement of coordination numbers, donor atom types and bond lengths of metal ions in multiple oxidation states which are generated electrochemically. We have demonstrated the applicability of this technique to study the redox coordination chemistry of metal ions in aqueous and nonaqueous solvents, ionically conducting polymer films, electroactive films on conducting metals and electrically conducting polymers. Our objectives were to conduct research in the following areas: (1) electrostatic cross-linking of ionic polymer films and their effects on the structures of charged coordination compounds immobilized in the film, (2) cation charge transport and its effects on the structures of electroactive films such as Prussian blue deposited on electrodes, (3)metal ions incorporated in electrically conducting polymers, (4) development of a flow cell which enables EXAFS spectroelectrochemistry to be performed in a controlled atmosphere environment, (5) structure determination for metals and intermetallic compounds in mercury solvent, and (6) evaluation of spectroelectrochemical nernstian plots.
