Abstract Scope |
The chemical synthesis of high-entropy alloy nanoparticles (HEA-NPs) retains the benefits of bulk HEAs while offering higher surface energy. This research focused on the sintering of Ni-Pt-Pd HEA-NPs synthesized by Fast Moving Bed Pyrolysis (FMBP), a method that produces contaminant-free, homogeneously distributed chemical elements and highly dispersed HEA-NPs. Our study employed in-situ Transmission Electron Microscopy (TEM) using a Protochips Fusion Select holder on a JEOL 2100, as well as ex-situ analysis using a JEOL ARM 200CF, Energy-Dispersive X-ray Spectroscopy (EDS) mapping, and X-Ray Diffraction. The results from both in-situ and ex-situ analyses demonstrated the sintering behavior and structural evolution of Ni-Pt-Pd HEA-NPs over time and temperature. |
