Lay Summary (English)

Lead
Lay summary
Photocatalytic oxidations and in particular photocatalytic water splitting is an attractive way to transfer the energy of sunlight into chemical energy, which can fuel combustion engines or fuel cells.

In this context the current project is aiming at the production, high-throughput screening and optimisation of photocatalytically active nano-structured materials. Fe-doped TiO2 is chosen as model system. The nano-particles of Fe-doped TiO2 will be produced by means of laser pyrolysis. In the first phase of the project this method will be established and a small number, but well characterised samples will be produced by the group of Prof. Ion Morjan in Bucharest, Rumania. The samples will be investigated with a scanning electrochemical microscope modified with an appropriate light source towards their oxidative power under illumination. At the same time sample preparation and the screening stage will be adapted to a high-throughput mode, which will enable us in the second phase of the project to screen a large number of samples in parallel. This work will be done at the University of Basel (Dr. E. Figgemeier and Prof. E. C. Constable).

In the last phase of the project, an additional photocatalytically active system will be selected, produced and screened towards oxidative and reductive power under sunlight illumination. Currently, nitrogen-doped

TiO2 seems to be an attractive candidate for its water splitting abilities and is therefore tested with priority.
