Finding better electrodes for sustainable water splitting
July 1, 2021
Water splitting with electricity is a key technology for renewable energy storage. When a voltage is applied to two electrodes immersed in water, the water splits into oxygen and hydrogen gas. This process is called electrolysis. The hydrogen gas can be captured and stored. It can be used in fuel cells, or for the production of sustainable chemicals.

What really happens at the surface: photoelectrochemical cells
December 7, 2020
Improving the efficiency of photoelectrochemical cells requires detailed understanding of all that is going on at the electrode surface. In an ACS Catalysis paper, the Bieberle group shows how a novel modeling approach not only explains what is happening, it can also guide selection of better performing materials.

Urban design software improves water splitting
March 13, 2020
A fresh look at photoelectrochemical cells may boost these devices' ability to convert sunlight into the clean energy carrier hydrogen. Researchers from DIFFER, Delft University of Technology and Twente University used carefully structured and measured photoelectrochemical cells in combination with software developed for urban design to explain why such cells only reach a fraction of their theoretical performance. It turns out that extending pillars on the cell surface can shadow each other, like skyscrapers in a busy city centre. The team published their research and a new design which may improve performance in the journal Advanced Functional Materials.
