Ph.D. Thesis:

Entwicklung und Anwendung der Operando Spektroskopie an Vanadiumoxidkatalysatoren in ODH Reaktionen: Ein Vergleich von O2 und CO2 als Oxidationsmittel

Development and Application of Operando Spectroscopy for Vanadium Oxide Catalysts in ODH Reactions: A Comparison of O2 and CO2 as Oxidising Agents

Marc Ziemba was awarded the Prize of “Freunde der TU” 4 December 2019 for his outstanding master thesis at Hess research group with the title: Investigations of the water gas shift reaction over faceted Au/CeO2 catalysts: Combination of operando spectroscopy and DFT calculations.

Member of the board Matthias Send presented the prize, which is endowed with 1,000 Euro, at the Eduard-Zintl seminar series.

On July 3, 2019, the Bottling Family Foundation awarded the prize of 3,500 euros for an outstanding doctoral thesis in the Department of Chemistry at TU Darmstadt. This year's prizewinner is Dr. Christian Schilling, who received his doctorate with distinction in the field of physical chemistry in the research group of Prof. Dr. Christian Hess.

His doctoral thesis entitled “Operando Spectroscopy and DFT Modeling of Gold/ Ceria Catalysts for CO Oxidation and Water-Gas-Shift Reaction” was characterized by demanding investigations using operando spectroscopy. He used this method to investigate oxidation reactions over ceria-containing gold catalysts in order to draw conclusions about the mode of action of this catalyst and to improve properties such as activity, selectivity and long-term stability. His work stands out in particular for its high intellectual level and an unusual degree of creativity in the autonomous conception and realization of complex research projects.

Award for excellent young researchers.

Dr. Christian M. Schilling was honored for his outstanding scientific achievements on May 16 at the Georg-Christoph-Lichtenberg Haus. The prize, which is endowed with 2,500 euros, is donated annually by the Friends of TU Darmstadt for the best dissertation in each of the TU Darmstadt faculties. Dr. Christian Schilling wrote his dissertation entitled “Operando Spectroscopy and DFT Modeling of Gold/ Ceria Catalysts for CO Oxidation and Water-Gas-Shift Reaction” in the Department of Chemistry, working group Prof. Christian Hess. Together with him, eleven other young scientists were honored for their excellent work.

The Chairman of the Friends of the TU, Matthias W. Send, presented the prize winners and their work in the ceremony. The prizes were presented in the presence of the Vice President of the TU Darmstadt, Prof. Matthias Rehahn, and the designated President of the TU Darmstadt, Prof. Tanja Brühl.
