Abstract

A novel electroactive nanostructured silver molybdenum oxyfluoride (SMOF) perovskite was successfully synthesized via mechanochemistry through the use of AgFx and MoO3. The structure of the SMOF perovskite has been examined utilizing X-ray powder diffraction (XRD) combined with X-ray absorption spectroscopy (XAS) and elemental analysis. The SMOF perovskite exhibited a very good electrochemical activity. A detailed in-situ electrochemical study by XRD and XAS was carried out. Finally, preliminary work on fabrication of a metallic Ag2F phase and optimization of the rate capability of SMOF perovskite is presented.
