My research interest deals about sol-gel synthesis of nanostructured (complex) metal oxides applied as photoabsorbers and electrocatalysts for photoelectrochemical water splitting. Nanostructuring provides for example short charge carrier transport paths, which are beneficial for several energy applications. Understanding the performance of novel energy materials requires a fundamental knowledge of both the bulk and surface properties. For analyzing the surface properties, such as the oxidation states and the energy levels within the semiconductor, photoelectron and Raman spectroscopy are utilzed, while the crystal structure und bulk properties are derived by methods such as X-ray diffraction. An overall thorough material characterization allows to correlate these physicochemical data with the performance for the specific energy application. It is the ultimate goal to improve the properties of energy materials through tailoring their structure and morphology on the nanoscale.
