ERC Consolidator Grant for HZB researcher Robert Seidel

The project is investigating nanoparticles that are used as catalysts in the production of "green" hydrogen

Physicist Dr Robert Seidel has been awarded a Consolidator Grant by the European Research Council (ERC). Over the next five years, he will receive a total of two million euros for his research project WATER-X. Seidel will use state-of-the-art X-ray techniques at BESSY II to study nanoparticles in aqueous solution for the photocatalytic production of "green" hydrogen.

With the Consolidator Grant, the ERC supports researchers with several years of experience who are now planning a large-scale research project. The physicist Robert Seidel is an expert in X-ray methods at BESSY II. In high-profile published studies, he has already shown that water still holds many surprises.

In his ERC project WATER-X, he is focusing on the process of photocatalysis, in which water molecules are split into hydrogen and oxygen. If the energy required for the catalysis comes from renewable sources, the hydrogen produced is considered "green". Hydrogen will play an important role in the fossil-free energy system of the future, whether as energy storage, fuel or raw material for industry. However, catalysts are needed for a highly efficient process, and this is where the WATER-X project comes in.

"In WATER-X, we will investigate the ultrafast processes on catalytically active nanoparticles in water that can be activated by light," says Seidel. While the entire photocatalytic water splitting process is relatively slow (milliseconds to seconds), the light-induced processes on the catalyst particles are so fast (picoseconds to nanoseconds) that they have been very difficult to study experimentally. The team will focus on four different transition metal oxides that can be activated by light (photons) and are considered interesting candidates for inexpensive and efficient catalysts.

 Seidel will investigate these picosecond processes at the interfaces of transition metal oxide nanoparticles in water by combining the "liquid microjet setup" at BESSY II with time-resolved femtosecond laser photoelectron spectroscopy. For the first time, short-lived molecular intermediates and their decay mechanisms could be precisely observed experimentally.

"At the end of the WATER-X project, we will understand the light-induced processes between catalyst nanoparticles and water much better and also, how to improve them," says Seidel. This could significantly accelerate the development of novel, highly efficient catalysts for many purposes, not just green hydrogen.

The development of the Science and Technology Park Berlin Adlershof was and is co-financed by the European Union namely by EFRE. This concerns infrastructure development like construction of technology centres. Furthermore EFRE is used for international projects.
