DIFFER Seminar: Inorganic nanomaterials from the gas phase - on the way to high-performance materials

Abstract: The growth areas of energy conversion and storage in particular have created a massive demand for new active materials in recent years. In the field of heterogeneous catalysis, transition metal compounds are of particular interest, if only for reasons of sustainability and availability. In the field of battery electric applications, the trend is towards materials with ever higher capacity and stability. In all cases, their manufacture using scalable gas phase synthesis is an attractive production process, as it enables the provision of complex materials with adjustable properties. Using the example of the oxygen evolution reaction, which is critical for electrochemical water splitting, it is shown how the targeted adjustment of the chemical composition can be used to design high-performance catalyst materials. Using the example of the production of silicon-based anode materials for Li-ion batteries, it is shown how new types of active materials can be produced by alloy formation during particle formation in the gas phase.
