Iron–molybdenum mixed oxides are well-established catalysts for the oxidative dehydrogenation (ODH) of methanol, but their performance in the ODH of ethanol (EtOH), particularly with respect to the Mo:Fe ratio, remains unexplored. In this study, we present the synthesis of mixed oxides across the full composition range, their catalytic assessment in the ODH of EtOH, and their structural characterization. While pure iron oxide is unselective toward acetaldehyde (AcH), introducing small amounts of molybdenum oxide enhances the catalyst's selectivity significantly. In contrast, molybdate-rich systems tend to produce more dehydration products such as diethyl ether and ethene due to an increased acid site density. The optimal catalyst was found to be an iron-rich system with a composition of x
