BioThe focus of my research is implementation of advanced methods to gain structural information from X-ray absorption spectra of heterogeneous catalysts under operating conditions. Structural dynamics can be very subtle and chemical structures yet unknown. By applying high-sensitivity detection methods (e.g. HERFD-XAS*) and theoretically calculating spectra of hypothetical structures, I enhance the sensitivity of conventional techniques and create shortcuts to new discoveries.
Particular systems of interest are single-site catalysts, serving as excellent models for examining reaction mechanisms and intermediate species on well-defined sites. Furthermore, I study activation and de-activation of catalysts for globally important energy-related processes.
