AB - The surface chemical composition of supported single Pt-Rh core-shell nanoparticles was studied to understand the Rh behavior in oxidizing and reducing gas environments using spectro-microscopy with high spatial resolution. We combined in situ X-ray photoemission electron microscopy with ex situ scanning electron-, atomic force- and scanning Auger-microscopy to distinguish Rh oxidation-reduction, dewetting-sintering and alloying-segregation during the course of the experiment.
