Abstract

Shape stability of Pd–Rh core–frame nanocubes was studied by in situ heating transmission electron microscopy. Pd–Rh nanocubes could maintain cubic shape at elevated temperature compared with pure Pd. The surface diffusion process of Rh onto {100} side surfaces is believed to postpone the degradation to higher temperature.
