Visualising redox-driven metal–oxide interface dynamics in Ni/GDC electrodes via in situ Auger–Meitner electron microscopy

Year: 2026

Type: article

Abstract: . In addition to Ni redistribution, pronounced ceria mobility is observed, including migration of a Ce-oxide species onto Ni under strongly reducing conditions, and Ce enrichment near Ni/NiO triple-phase boundaries under oxidising conditions, thus highlighting the active role of the oxide support in redox-driven morphology evolution.
