Abstract The structural and morphological characterization of individual catalyst particles for olefin polymerization, as well the reverse process polyolefin decomposition, can provide an improved understanding how these materials operate under relevant reaction conditions. In this review, we discuss emerging analytical toolbox 2D 3D chemical imaging techniques that is suitable investigating chemistry reactivity related systems. While synchrotron‐based X‐ray microscopy still provides unparalleled spatial resolutions in 3D, a number laboratory‐based techniques, most notably focused ion beam‐scanning electron microscopy, confocal fluorescence infrared photoinduced force nano‐computed tomography, have helped to significantly expand arsenal tools available scientists heterogeneous catalysis polymer science. terms future research, review outlines role impact situ operando (spectro−)microscopy experiments, involving sophisticated reactors online reactant product analysis, obtain real‐time information on formation, mobility phases within single particles. Furthermore, potential optical highlighted high‐throughput polymerization decomposition catalysts. By combining with, example, staining methodologies, selective probe molecules particle sorting approaches, representative structure–activity relationships be derived at level
