Title:
Catalytic Photochemistry at Semiconductor Surfaces

Abstract:
Utilization and storage of solar energy using chemical processes is a
major challenge. A promising method is the use of semi-conductor
photocatalysis, in which similar to photosynthesis a heterogeneous redox
reaction converting solar energy into chemical energy takes place.
Thereby, novel routes of synthesis for atom-economic addition reactions of unsaturated organic compounds can be developed. Furthermore,  photo fixation of atmospheric nitrogen on thin semiconductor films as well as   the complete photo-catalyzed degradation of air pollutants by modified titanium dioxide powder even in diffuse indoor daylight is possible. Finally, functional surfaces on the basis of semi-conductors can have bactericidal properties.
