A happy medium : Volumetric adsorption of carbon monoxide at 308 K and UHR‐HAADF‐STEM, HREM, and computer modeling techniques were compared. Experimental CO/Au ratios at saturation coverage for two supported gold catalysts were shown to fit very well the predictions of a nanostructural model that considers CO adsorption on gold sites with coordination numbers of less than eight.
