„Model-based scalable gas-phase synthesis of complex nanoparticles“ Project „Mass spectrometric characterization of the precursor chemistry and particle growth in flame reactors“
The formation of nanoparticles from the gas phase is a strategic research focus at the University of Duisburg-Essen. Research activities are coordinated by the CENIDE network. Through my continued membership in CENIDE, I have developed an interest in the investigation of the chemical basis for the formation of nanomaterials from the gas phase.
Organometallic compounds are often used as precursors for the high-temperature synthesis of nanoparticles in the gas phase. Despite the substantial influence of the precursors on the synthesis process and the nanoparticles, the gas phase chemistry and the interaction of the precursors with the species pool in the synthesis flames is poorly understood. My research group has investigated these topics experimentally and the data obtained were the basis for the development of reaction mechanisms to describe precursor decomposition and particle formation in cooperation with partners in the research group. The overall aim of the research group was to understand the synthesis process in detail on all size scales and to describe it as a model in order to achieve systematic scalability of the synthesis from laboratory scale to pilot plant scale.
