Quantification of individual defects: The study describes an analytical route toward a detailed and quantitative description of individual defects in heterogeneous catalysts. The investigation is based on high resolution scanning transmission electron microscopy (STEM) imaging using complex (Mo,V)Ox mixed oxide as an example. Tiling the structural regions simplifies the identification of local modifications in the microstructure. Using this technique we observed 19 different localized and extended structures that can be listed and classified into different structural motifs, intergrowth, channels, interstitial regions, and inclinations.
