Fig. 5

Simulated ADF STEM images and corresponding EDX maps of 6 nanoparticle structures tilted by 5° from the 100 zone axis towards the 111 zone axis: (2) Pt edges, (3) Pt hexapod, (4) Pt hexapod and edges, (5) Pt hexapod, edges and core, (6) Ni facets and (7) alloy. The Pt-L signal is shown in red, while the Ni-K signal is shown in green. The white arrows highlight regions in the EDX maps where the Pt hexapod structure (3) begins to deviate from the Ni facets structure (6)
