| Abstract: | We report the first grain-resolved mapping of oxygen evolution reaction (OER) activation on a Ni-based superalloy using identicallocation EBSD, complemented by IL-SEM, IL-EDS, and SECCM. NiFe (oxy)hydroxide film formation and OER activity are strongly influenced by grain size and orientation, with (111)-oriented and smaller grains showing the highest activity. These findings reveal pronounced microstructure heterogeneity and establish IL-EBSD as a powerful tool for guiding the design of advanced electrocatalysts. |
