ERC Consolidator Grant for HZB researcher Robert Seidel The WATER-X research project is funded by the EU under the project number 101126299.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 WATER-X research project is funded by the EU under the project number 101126299.Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are suitable for many applications, from biomedicine to environmental engineering and energy technologies. An article in "Nature Reviews Methods Primer" now provides a guide to freeze-casting methods that includes an overview on current and future applications and highlights characterization techniques with a focus on X-ray tomoscopy.The IRIS infrared beamline at the BESSY II storage ring now offers a fourth option for characterising materials, cells and even molecules on different length scales. The team has extended the IRIS beamline with an end station for nanospectroscopy and nanoimaging that enables spatial resolutions down to below 30 nanometres. The instrument is also available to external user groups.Inorganic perovskite solar cells made of CsPbI 3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI 3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.#J-18808-Ljbffr
