Electrosynthesis of Energy Carriers & Value-Added Products
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.
Congratulations to Yang, Patrick and Attila for getting their their paper on miniature Ag/AgCl reference
electrodes for aqueous and organic electrolyte accepted in ChemElectroChem! We hope these new
devices can support the research of beginners, student lab courses, and experts in electrochemistry.
We welcome Felix Yue for his bachelor thesis on electro-hydrogenation, targeting alternative
mechanisms with Ir-pincer catalysts in acidic conditions, as well as new cobalt catalysts. Best of luck
and enjoy your stay with us!
Two of our papers made it out to review before the X-mas break. Everybody keep your fingers crossed
for our first-authors Patrick and Yang!
Welcome to Giannis, who now arrived at TUM to study his first-row transition metal complexes bearing metal-arene bonds with us. Best of luck and enjoy your ERASMUS+ stay!
Our second collaboration here at TUM with Roland Fischer and Alexander Pöthig on electrically conductive MOFs, enhanced by metal-sulfur bond covalency is now accepted in Inorganic Chemistry. Congratulations to the first author Margit Aust and thanks for the exciting work together!
Whoohoo! Our First TUM callaboration with Angela Casini and Denise Lovison is just accepted in ACS
Catalysis! Such multi-dimensional work in one paper covering ruthenium coordination chemistry,
transfer hydrogenation catalysis, electrochemical investigations, and anti-cancer studies is only
possible in a great team with talented collaborators. 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!
Great news: Our talented master student Tianyin Huang was awarded a prestigious fellowship of the
CSC high level PhD program, to do his PhD in our group. We are looking forward to some electro-
hydrogenation of arenes :).
A new group member and a new paper! Welcome Yi-Pin (Anthony) Wei who joined our team for a
research internship, studying mixed metal nickel/cobalt materials for electro oxidation catalysis with
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.
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!
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!
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
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
Combining the outstanding work of master student Patrick Mollik and research intern Alexander
Frantz, we have now submitted the group's first paper on electro-hydrogenation for review
and deposited the pre-print on ChemRxiv: DOI: 10.26434/chemrxiv-2022-5r738
Further great news are that Alexander thinks "all good things come in threes" and re-joins our group
for the third time, to now do his master thesis with us. He will explore cationic electro-hydrogenation
catalysts with drastically reduced overpotentials. Best of luck Alex, keep the papers coming ;)
Finally, we welcome Noah Richter to the group as a research intern, to kick off our first project on "not
atomically precise" electrocatalyst materiasl ;). Best of luck Noah!
A new collaboration with the Pöthig group here at TUM is initiated, to study electrochemistry and
redox properties of supramolecular compounds. It is exciting to see the first results come in!
New team members arrived! We welcome Pascal Fink for his master thesis on electrocatalytic oxygen
transfer reactions, and Tianyin Huang for his research internship on structure-reactivity tuning of
molecular electro-hydrogenation catalysts. Best of luck to both of you!
It is safe to say that Patrick has evolved into an expert for LIDFI-MS analysis of in situ produced
catalyst species to detect key intermediates in electro-hydrogenation. The powerful method will be of
long-term importance for our lab!
We are very happy that Alexander Frantz chose to continue working with us for his "Catalysis Research
Internship". As a by now experienced electrochemist in the group, he forms a strong team with Patrick
to finalize work on our group's first project.
After months of project planning, proposal writing, and remote discussions between Garching and
Budapest, it is exciting to now welcome Attila to our group in person, currently as a research intern.
With several people working on electro-reductions, it is a huge step forward for us that now Attila gets
the ball rolling on electro-oxidations with molecular catalysts. Best of luck!
Whohoo! Yang arrived in Garching and started strong with his first MOF syntheses and derivatization
steps. Looking forward to see the catalysis in action! Best of Luck for your PhD Yang, it is awesome to
have you on our team!
Welcome to Huy Hai-Dang Phan aka Victor, who joined us for his bachelor's thesis project on electronic
strucutre tuning of molecular hydrogenation electrocatalysts. After fruitful discussions and project
planning, It is awesome to finally have you on board, best of luck!
Two new team members have joined this summer: Alexander Frantz for a research lab course project
to study the electrochemistry of multiple catalyst variants that he & Patrick made, and a brand new
PalmSens4 potentiostat. Exciting times ahead, GO Team!
We are thrilled that with Richard Zell a second master student has jouned the team! Richard will
investigate innovative substrates to enable a drastic process simplification for renewable energy
storage based on electrocatalytic hydrogenation. Welcome Richard and best of luck!
Very proud to share the good news: Yang Lyu was awarded a prestigious CSC Scholarship and will join
the group as a PhD Student in September to work on solid state electrocatalysts for site selective
