We present the atomic structure of Ir nanoparticles with 1.5 nm diameter at half height and three layers average height grown on graphene/Ir(111). Using surface x-ray diffraction, we demonstrate that Ir nanoparticles on graphene/Ir(111) form a crystallographic superlattice with high perfection. The superlattice arrangement allows us to obtain detailed(More)
The supplementary material summarizes the following complementary fit results: from an area on the surface several mm away from the LSC electrode for three different conditions and for the UHV prepared clean YSZ (100) surface (see Table 1). In Figure 1 the corresponding occupancy profiles are shown. Figure 2 and 3 show the corresponding experimental data 1
Nanoparticle sintering during catalytic reactions is a major cause for catalyst deactivation. Understanding its atomic-scale processes and finding strategies to reduce it is of paramount scientific and economic interest. Here, we report on the composition-dependent three-dimensional restructuring of epitaxial platinum-rhodium alloy nanoparticles on alumina(More)
