After undertaking his BSc project and working as a research intern, Zaid Wonde leaves the Kühnel Lab after 18 months to continue his studies in microbiology. Nils Weimper leaves the lab after 6 months as a research intern to undertake his MSc project with Fabian Commichau. We will miss you guys!

Taylor Frost starts her interdisciplinary MSc project on photoreforming in collaboration with Sven Marhan in Soil Biology. Ellen Lambur starts as lab technician. Welcome to the Lab!

Atekelte Kassa leaves the lab to undertake a PhD in physics at the University of York.

Léonard’s article about the mechanistic details of semiconductor–enzyme hybrid photosystems was published in Trends in Chemistry (read his paper here). The paper highlights exciting work from the Dukovic group at Boulder that examines the various competing electron transfer pathways in biophotocatalysts that are unobservable by direct means. Using kinetic modelling, the work shows how often overlooked pathways such as back electron transfer and reverse reactions are key for achieving a high activity (read original paper here).

After a long review process, our joint paper with the Kornienko Lab in Bonn was finally published in Nature Chemistry (read paper here). The first experiments were performed by Max Kutter back in 2018! The paper shows how a mediocre homogeneous catalyst was turned into a highly active hetrogeneous electrocatalyst for CO₂ reduction through the use of fluorine chemistry. Making a molecular cobalt terpyridine catalyst highly hydrophobic enables it to self-assemble on the surface of a gas-diffusion electrode, which alters its product selectivity from CO formation to the selective formation of CH₄ at high current densities. We show that in this environment, proton transfer occurs via terpyridine ligands serving as a proton conduit. Free access to the paper is available here.

The Kühnel Lab is looking for a motivated German-speaking PhD candidate (TVÖD E 13, 50%). We value team spirit, open communication and ambition. The successful candidate will work experimentally in the field of artificial photosynthesis e.g. on the synthesis and characterisation of materials and/or coordination compounds and performance testing as potential photo/electrocatalysts. The role includes duties in the organisation and teaching of the Department of Inorganic Chemistry, e.g. lab demonstrating. Applicants must hold a masters in chemistry or equivalent degree in a related discipline and must be fluent German speakers. The ideal candidate can demonstrate enthusiasm for research, motivation for acquiring new synthetic/analytical techniques and people skills. Experience in electrochemistry, photocatalysis and gas chromatography are desirable. Applications must be made in German via the online portal by 31/8/2024 (link).
