In situ surface X-ray diffraction using a new electrochemical cell optimised for third generation synchrotron light sources

Abstract

Thanks to the new third-generation high energy synchrotron radiation sources it is now possible to study electrochemical interfaces in situ using a cell fulfilling all the electrochemistry requirements. We are presenting here one version of this cell type, especially designed for surface X-ray diffraction. Its geometry allows in and out of plane data collection with the voltammetry fully controlled at any time. Fresh results concerning the gold (1 1 1) surface evolution in diluted H 2SO 4 electrolyte are presented. Finally, the perspectives opened by this in situ studies are discussed.
