Our research is focused on the development of functional oxide-based materials for solar energy, sensors and water cleaning applications. Synthetic targets are nanoscale oxides and polyoxometalates (POMs) which are accessed with clear-cut and scaleable procedures. We explore different strategies towards visible-light-driven water oxidation catalysts (WOCs): homogeneous POM-assisted processes,^[1] heterogeneous nano-oxide WOCs,^[2] and doped ceria materials for thermochemical water splitting. Special emphasis is placed on the role of mixed transition metal centers and on genuine active species in the catalytic process. Research on sensors and wastewater treatment catalysts is centered around Bi-containing oxides. Mechanistic tracking of their growth pathways leads to systematic performance optimization.

Furthermore, we investigate the high application potential of bio-active POMs as new and low-cost antiviral and anticancer agents using drug carrier techniques with biopolymers.^[3]
