The presentation reports on novel Soft X-ray Fresnel CDI ptychography results, demonstrating the potential of this method for dynamic studies. Our in-situ ptychography experiments explored the electrodeposition process of Mn and Co/polypyrrole (PPy) nanocomposites, Pt-free candidates for fuel cell catalysts . The measurements were performed using a custom-made three-electrode microcell . The cell has been developed at the TwinMic beamline of Elettra during a series of experiments that were continued at the SXRI beamline of the Australian Synchrotron . The ptychography-based investigation of the electrodeposition dynamics was executed during the in-situ electrical biasing of the electrochemical cell. Besides the observation of morphological changes, we retrieved the spectroscopic information, provided by multiple ptychographic energy scans across Mn and Co edges. The most important issues related to the computational aspects of such experiments will be outlined and potential improvements of the methodology will also be discussed.
