nanoparticles on the STO support are observed to sinter under identical oxidizing and temperature environments. A nanoparticle facet-dependent analysis of selected Pt-core nanoparticles suggests that Rh oxidation is most advanced on a small nanoparticle with a low coordination top facet that we indexed by electron backscatter diffraction, demonstrating the strength of our correlative approach.
