Converting solar energy and storing it in form of solar fuels, is one of the great scientific and technological challenges today to enable the transition into a more sustainable future powered by renewable energies. Scientists at the HZB institute for Solar Fuels are exploring new semiconductor materials in order to develop compact, robust and economic solutions for “artificial photosynthesis”. They have submitted four research projects in collaboration with partners from universities for funding by the German Research Association (Deutsche Forschungsgemeinschaft DFG) in the Priority Programme „Fuels Produced Regeneratively Through Light-Driven Water Splitting” (SPP 1613). All four projects have now been approved for funding.
“A success rate of 100 percent in this highly competitive call is truly remarkable, since only half of the submitted proposals could be funded”, Professor Roel van de Krol, head of the HZB Institute for Solar Fuels states. “This means we can further strengthen and expand our institute’s activities”. The first three projects are extensions of already running projects, while the 4th one is a new activity.
The objective is to investigate artificial photosynthesis based on solid-state inorganic materials from a fundamental scientific perspective as well as the aspects of material science required for its technological implementation. The goal is to convert solar energy into storable fuels, in this case hydrogen, which has a high gravimetric energy density and can be safely stored and used whenever needed, either in a fuel cell to generate electricity or as a base component for the production of synthetic hydrocarbon fuels.
The approved projects are:
- Development of catalysts, namely manganese oxides and molybdenum sulphides, for an implementation in a light-driven water-splitting device using a multi-junction solar cell. Partner: Prof. H. Dau (PI, FU-Berlin), Prof. P. Kurz (University Freiburg i. Br.), Prof. S. Fiechter (HZB).
- High-throughput characterization of multinary transition metal oxide and oxynitride libraries. New materials for solar water splitting with improved properties. Partner: Prof. Wolfgang Schuhmann (PI, Ruhr University Bochum), Prof. Alfred Ludwig (Ruhr University Bochum), Prof. S. Fiechter (HZB).
- Novel thin film composites and co-catalysts for visible light-induced water splitting. Partner: M. Behrens (Uni Duisburg), A. Fischer (Uni Freiburg), M. Lerch (TU Berlin), T. Schedel-Niedrig (HZB).
- Development of optimum bandgap photoanodes for tandem water-splitting cells based on doped complex metal oxides and III-V semiconductors coupled to water oxidation electrocatalysts. Partner: R. Beranek (PI, Ruhr University Bochum), A. Devi (Ruhr University Bochum), R. Eichberger (HZB).
- HZB congratulates Peter Hegemann on winning the Nobel PrizeOur warmest congratulations go to Peter Hegemann, Professor of Neuroscience and Experimental Biophysics at Humboldt University in Berlin. Together with Prof. Georg Nagel (Julius Maximilian University of Würzburg) and Prof. Karl Deisseroth (Stanford University, USA), he has been awarded the 2026 Nobel Prize in Physiology or Medicine. We are delighted for him, his team, Humboldt University and the entire Berlin scientific community.
- Does African Architecture exist?The world’s first Pan-African Architecture Biennale took place this September in Nairobi, Kenya. People from the worlds of architecture, art, academia and politics from 54 African countries and the diaspora had travelled to Nairobi to exchange ideas on traditional and contemporary building methods, materials, experiences and projects. Samira Aden co-organised this biennial as lead curator. We spoke to her about it.
- Nanosilver as an electrocatalyst for CO₂ reductionVia electrolysis, CO2 can be reduced to CO, a raw material for further chemical products such as fuels. Within the GreenQuest Project, an internation team led by HZB chemist Prashanth Menezes has now systematically investigated catalyst layers made of silver nanoparticles, varying both the size of the particles and their density. The best yield was achieved with nanoparticles with diameters of around 10 nm, which were loosely distributed. Furthermore, they demonstrated how the economic efficiency of the electrochemical cell can be enhanced by integrating an additional chemical reaction at the anode, enabling the simultaneous production of a valuable formic acid, hydrogen, and CO in one device.
