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.
