Report introduction

Abstract:

Heterogeneous catalysis significantly shapes society, as it plays a   crucial role in the production of base chemicals, fuels for mobility and specialty   chemicals and protection of the environment. Fischer-Tropsch synthesis is an   increasingly important process for the production of fuels and chemicals from   a variety of feedstock. Our working approach is to combine advanced kinetic   and spectroscopic methods with theoretical studies. By combining advanced   kinetic investigations on cobalt model systems with theoretical studies, we   can understand the fine details of converting synthesis gas to hydrocarbons.   Recently, we have developed strongly improved iron-based catalysts that   approach cobalt-based systems in terms of performance. These insights can be   extended to CO₂ hydrogenation to methane, relevant to energy   storage, for which manganese promotion of nickel will be highlighted.   Besides, the highly dispersed, possibly isolated atom nature of the metal   phase in ceria-supported Pd catalysts has been emphasized. We combine   computational modeling with near-ambient pressure XPS and operando IR   spectroscopy to investigate nanostructured ceria models. Our work highlights   the dynamics of the Pd phase. A computational approach is developed to   predict the composition of small supported Pd clusters in a reactive oxygen   atmosphere. These methods are then applied to understand the positive effect   of a ceria support on gold clusters for CO oxidation.
