Back Cover: Hidden Impurities Generate False Positives in Single Atom Catalyst Imaging (Angew. Chem. Int. Ed. 44/2024)

Isolated metal atoms of a single‐atom catalyst are represented on the cover as distinct dots, reflecting their usual appearance under a microscope. However, as detailed in the Research Article by Gianvito Vilé, Sean M. Collins et al. (e202404883), hidden impurities can lead to false positives in imaging. Accurate differentiation between active catalytic sites (in black) and impurities (in blue) can only be achieved by combining microscopy with in situ electron energy loss spectroscopy, which sets new standards for advanced detection techniques in single‐atom catalysis.
