Zusammenfassung:As good as atomic gold: Aberration‐corrected scanning transmission electron microscopy images of zeolite NaY‐supported mononuclear gold complexes, obtained with atomic resolution of the gold atoms, showed the locations of the gold complexes in the zeolite framework (see picture) and identified them as the catalytically active species for CO oxidation at 298 K and 1 bar.
