Thermal Catalysis: Activity and Selectivity Patterns of Transition Metal Oxides in Different Oxidation Reactions
Project A1 focusses on thermal catalysis in the liquid phase under mild conditions using the mixed iron-cobalt spinel and perovskite catalysts synthesized in Area C with well-defined real structure. Isopropanol, cyclohexane and cyclohexene will be oxidized with O2 as the main oxidant using H2O2 and tert-butyl hydroperoxide in addition. The toolbox of gas-phase methods including temperature-programmed methods for the determination of the redox properties and probe molecules to assess acid-base properties will be applied to the Co1+xFe2-xO4 and LaCo1-x FexO samples. Together with the results obtained from Area B, structure-activity correlations will be established.
