Development of Methods and Devices for Spatially and Temporally Resolved X-Ray Microscopy for Characterization in Heterogeneous Catalysis

Characterization of catalyst materials and unraveling of catalytic processes requires a multitude of complementary and in situ techniques. In this work, analytical methods are developed based on X-ray microscopy: quasi in situ tomography to study honeycomb aging and ptychography to image nanoparticles. Moreover, devices are designed to enhance temporal and spatial resolution: a microfluidic chip to study Au nanoparticle formation and a gas phase microreactor for in situ catalytic experiments
