Abstract
Stable and efficient catalytic architectures are a prerequisite for artificial photosynthesis. In order to achieve sustainable energy conversion and storage into chemical bonds, it is instrumental to understand the chemical transformation of these catalytic architectures under operating conditions. Our group uses different strategies to understand how the performance of a (photo)electrode is impacted by chemical transformations during operation. Specifically, we look at how functional, chemical, and structural heterogeneity over different length scales influences macroscopic performance and stability. Here, we will show how we combine photoelectrochemical measurements with atomic force microscopy based techniques, and scanning transmission X-ray microscopy to gain a complete understanding of different material systems, such as bismuth vandate, copper oxide, and gallium nitride, for their application in artificial photosynthesis.
