| Abstract: | Prospect of probing an electrochemical interface in situ, under actual operating conditions, and ability to map both the substrate (in terms of its electronic and short range atomic order) as well as the substrate-adsorbate interactions has tremendous technological implications. Synchrotron based x-ray absorption techniques offer such an opportunity as a consequence of the unique characteristics of the synchrotron source. These include higher: intensity (104 higher), collimation, polarization, and pulse time structure enabling true in situ interfacial measurements. X-ray absorption spectroscopy and scattering have recently evolved as a true in situ probe for electrochemical interface with both model and commercially relevant nano dispersed materials, providing a unique perspective on both the short and long range atomic order as well as the changes to the chemical environment of the absorber. This together with some new developments in the data analysis and modeling has now enabled more detailed perspective on the surface adsorbed species. [ABSTRACT FROM AUTHOR] |
