Graphical Abstract
  • characterization of samples after the catalytic reaction, which cannot be characterized by the capacitance ratio method. For further characterization of the samples, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) measurements were performed to determine the surface morphology

  • by using scanning as well as transmission electron microscopy to examine their structure. Cross sections of silver nanoparticles, prepared for analysis by transmission electron microscopy were additionally studied by energy-dispersive X-ray spectroscopy in order to probe their chemical composition
  • energy-dispersive X-ray spectroscopy (EDX). These studies were performed both on a single-particle level as well as on particle arrangements or films.

  • , the contact area of particle and substrate is clearly dependent on the initial size of the colloid. Finally, the distribution of the Pt precursor inside the colloidal particle may also play an important role. To clarify this last point, TEM and EDX (energy dispersive X-ray spectroscopy) investigations

This difference is not a conflict between EXAFS and EDS results, but simply reflects the fact that an averaging technique such as EDS does not
