Institute of Engineering Thermodynamics
Area of research:
The institute is working on the utilization of technologies of energy conversion that are efficient and gentle on resources as well as on the accelerated utilization of renewable energies. In the section Electrochemical Energy Technology cost-effective and efficient solutions are elaborated for electrochemical energy storage and energy conversion. Flame spray pyrolysis (FSP) is one method for reliable and scalable production of nanomaterials and enables access to a broad range of nanomaterials. In contrast to conventional batch based synthesis methods, FSP is a continuous ﬂow technique requiring relatively simple apparatus that can be easily scaled up with a productivity of numerous kilograms per day.
Furthermore, the chemical and physical properties of the final products synthesized by FSP can be easily controlled by modification of the composition of precursor solution and process parameters (drop size, residence time, temperature etc.). This makes FSP particularly useful for preparation of nanocomposites including components such as noble metals, simple and complex metal oxides, carbonates, phosphates, and titanates.
Main goal of this doctoral thesis is to establish the FSP method at the DLR-Institute of Engineering Thermodynamics. The possibility of reliable and adaptable production of specialized nanomaterials will be implemented in the material development activities in different energy converter technologies under investigation. In addition, several nanomaterials classes of interest for in-depth research have to be identified and developed to improve future energy converters. An important aspect is a reliable synthesis of theses nanomaterials by FSP and the systematic modification of physical and chemical material parameters. With these results a development of structure-activity relationship models for catalyst systems and an improvement of the understanding of mechanisms for catalytic conversion and for degradation phenomena are foreseen.
