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.
