Thermal stability of Pd-Au core-shell nanostructures in an in-situ liquid TEM

Abstract The investigation of the thermal stability and evolution of Pd-Au core-shell nanostructures across various temperatures proceeded with in situ heating transmission electron microscopy (TEM) along with spectral analysis techniques. In situ heating transmission electron microscopy (TEM) was utilized to examine the morphology and elemental distribution of core-shell nanostructures composed of Pd 0.5 -Au 0.5 and Pd 0.9 -Au 0.1 , which were synthesized via the seed growth technique. Compared with the Pd 0.5 -Au 0.5 core-shell nanostructures, the Pd 0.9 -Au 0.1 core-shell nanostructures have better thermal stability.
