Abstract:
The performance of electrocatalysts depends on material properties that may differ spatially even within a single particle. Now, a combination of operando microscopy techniques is used to correlate morphology and metal oxidation state with local activity of an oxygen evolution catalyst, which may help to guide future catalyst design.
