The photochemical conversion of solar energy into chemical fuels is currently one of the most topical research areas due to its potential contribution to the future energy supply of our society. This technology strongly relies on the development of efficient, stable, inexpensive and environmentally friendly catalysts to convert sunlight, water and CO2 into carbon-neutral liquid fuels. Metal oxide based semiconductors are among the strongest candidates for this role and an in-depth understanding of how optical, electronic and structural properties determine the catalytic activity and stability of these materials is crucial for the knowledge-based development of optimised photocatalyst designs.



The PhD project will focus on the application of a combination of scanning probe microscopies (atomic force microscopy, tip-enhanced Raman spectroscopy), spectroscopies (UV/Vis/NIR, Fluorescence, Raman) and photoelectrochemical characterizatechniques to obtain a more detailed insight into the reaction mechanisms and unveil the significant structure-activity relationships in metal oxide based photoelectrocatalysis. Preparation and characterization of suitable semiconductor materials as well as the spectroscopic investigation of photocatalytic events on the solid/liquid interface on a single catalytic particle level will set the framework for innovative contributions to this emerging field.

The PhD candidate will be part of the newly formed Solar Fuels & Photocatalysis group and his/her involvement in setting up a new dedicated lab is strongly encouraged.
