    Structural analysis of catalytic materials

    My research focuses on the advanced characterization of structure-property relations in heterogeneous catalysts over relevant time and length scales. Microscopy techniques play a central role and an important achievement has been the development of integrated approaches to visualize technical zeolite catalysts, an area that I currently pursue with Bego and Antonio. As microscopy responsible, I regularly team up with other group members and also staff at the Scientific Center of Optical and Electron Microscopy of ETH Zurich on the visualization of zeolites, organic-inorganic hybrids, mixed metal oxides, and other novel catalysts. Similarly, I collaborate with Robbie and the group of Dr. Paolo Crivelli (D-Phys) to explore the potential of positron annihilation lifetime spectroscopy and with Micromeritics to develop improved gas sorption methods for the analysis of complex porous materials. Together with an industrial partner, Ferdy and I are using this knowledge to develop zeolite-based catalysts for vitamins synthesis. An exciting new area concerns the design of single site catalysts for hydrogenations in which I work with EvgeniyaDavide, and Zupeng.
