Iron molybdates are well-known as catalysts for the selective oxidation of methanol, whereas the role of their iron atoms is discussed controversial. Also, the oxidation of ethanol, particularly for a sustainable production of chemicals, is an important process. We will develop two operando setups in which Raman/XRD and Raman/Mössbauer are coupled under reaction conditions to identify the (iron-related) processes at the (sub )surface and bulk of iron-containing catalysts, and we will develop structure-performance reationships. The profound analyses in cooperation with other A projects will lead to a fundamental understanding of the role of iron in the selective oxidation of alcohols.
