Rational catalyst design is the holy grail of modern catalysis, which requires a thorough understanding of structure-performance relationships. Micro- and spectroscopy plays a pivotal role in the study of these relationships through the visualization of both the diffusive species, such as reaction products, and the pore network of a catalyst particle . A single micro(spectro)scopic technique is not capable of capturing the dynamics and many length scales involved, which can be overcome by combining various imaging techniques in a correlative manner. Despite that correlative microscopy is a rich research field for biological samples, it is largely unexplored in the area of materials science . The rapid developments in 3D super-resolution fluorescence microscopy, 3D X-ray microscopy, and 3D electron microscopy techniques hold great promise for the development of correlative microscopy to study inorganic materials [3-5]. The aim of this research project is the development and use of a combination of different microscopy and spectroscopy techniques to study structure-performance relationships in single porous catalyst particles.
