Overview of our research interests

h3v

Renewable energy conversion and storage are relevant topics in applied research today, since the use of non-fossil energy sources is essential for the reduction of CO2 emissions. Solar and wind energy harvesting combined with chemical energy storage in batteries or fuels like hydrogen are essential processes, which need to be improved in efficiency, long-term stability and scalability. Our goal is to contribute to the development of cost effective scalable solutions for energy conversion and storage.

Synthesis and Structure of the Double-Layered Sillén–Aurivillius Perovskite Oxychloride La2.1Bi2.9Ti2O11Cl as a Potential Photocatalyst for Stable Visible Light Solar Water Splitting

Exploring novel photocatalysts for solar water-splitting is a relevant measure to take towards sustainable hydrogen production. In this work, a fully titanium-based oxychloride, La2.1Bi2.9Ti2O11Cl, with a double-layered Sillén-Aurivillius intergrowth structure is fabricated via a facile one-step solid-state synthesis. A detailed crystal structure analysis is performed via powder X-ray diffraction and correlated to density functional theory calculations, followed by the demonstration of its photocatalytic activity for visible light-driven water oxidation.
