Electrosynthesis of Energy Carriers & Value-Added Products

We work on a shortcut to the H2 economy
Welcome to the Halter Group! Our reseach combines classical organometallic synthesis with materials science, to develop atomically precise electrocatalysts for the efficient laboratory scale electro-synthesis of organic energy carriers and value-added products. Specifically, the electrocatalytic hydrogenation (ECH) of organic compounds is a key interest, as ECH is a highly auspicious strategy to directly convert renewable electricity into chemical energy carriers and fine chemicals, without the challenging complications of handling and storing gaseous H2 at any point.

It was a pleasure to contribute, and we will see what comes next! Ioannis "Giannis" Vagiakos, a very talented Studend from the befriended Tsoureas group at the University of Athens was just awarded an ERASMUS+ Fellowship to join our team here at TUM in October for a four-months research stay. Giannis, we are excited to host you and look forward to be inspired by the low-valent titanium chemistry you bring to our lab!

Welcome Yi-Pin (Anthony) Wei who joined our team for a research internship, studying mixed metal nickel/cobalt materials for electro oxidation catalysis with Helena. In collaboration with Judith Riedhammer and Karsten Meyer (FAU Erlangen), Dominik's first Review as a corresponding author is now accepted in Chemical Reviews. A systematic analysis of electrochemistry data of over 200 uranium complexes allowed us to derive a new set of uranium calibrated ligand field parameters that now allow precise predictions for reactivity and redox potential tuning by ligand field modifications. November 2022: A very warm welcome to Junhong Chen, who joins us as a isiting researcher and prospective PhD student! Junhong finished his master's degree with great success at the Technion in Haifa and will start working on developing new pathways for ketone electro-hydrogenation. Best of luck Junhong! October 2022: Another awesome Update from Helena: it was just announced that she was awarded a prestigious PhD Fellowship by the DBU (Deutsche Bundesstiftung Umwelt), to fund her PhD project on electrocatalytic oxidation reactions with water. We are very happy to have your position in our team secured for the upcoming years now! April 2022: After many months of online ZOOM group meetings, we are thrilled to welcome Helena Pletsch to our team! After obtaining her master's degree in chemical engineering from the University of Sao Paulo, Helena joined us as visiting researcher and prospective PhD student in chemistry here at TUM. She will work on electrocatalytic oxygen atom transfer reactions, mediated by transition metal electrodes and MOF materials. It took a lot of effort from many people involved, but FINALLY ;) our new laboratory in the second floor of the CRC is fully equipped and ready to use! It is awesome to unite the team in one lab now, and we are very very grateful for the tremendous support by the CRC and by Prof. Roland Fischer and his chair! A great occasion to start the lab-bbq season for this year with a big kick-off event hosted by us ;).
