Electron Microscopy

Advanced electron microscopy of catalytic materials

Visualizing the structure of catalytic materials with atomic precision, under operating conditions and in 3D using advanced electron microscopy techniques is one of the main focus areas of the Materials Chemistry and Catalysis group, and an essential step in understanding how catalysts work. This effort is led by Jessi van der Hoeven and Petra de Jongh.

Our capabilities span in situ gas phase, in situ liquid phase, electron tomography, aberration corrected microscopy, HAADF-STEM imaging, EDX elemental mapping, FIB-SEM tomography, (cryo-)TEM and SEM. We are the key users of two Electron Microscopes (TalosL120C and TalosF200X) and through collaboration in the Electron Microscopy Center at Utrecht University we have access to wide range of other high-end TEM and SEM microscopes. Additionally, we develop in-house image processing tools to quantitatively analyze our microscopy data. Interested in collaborating? Please contact j.e.s.vanderhoeven@uu.nl or p.e.dejongh@uu.nl.
