Title: Visible light photocatalytic activation of C-H bonds via Ta2O5 and TiO2

GRK 2226 – Chemical Bond Activation (DFG)


Getting away from fossil fuels has become an urgent task, since worsening the global pollution indicates an upcomming climatic crisis. From 1970 onwards, photocatalytic water splitting via metal oxides has raised attention in the scientific environement due to it‘s capability of producing hydrogen as clean fuel out of water using sunlight.


Tantalum oxide is a well known photocatalyst for the UV light range. Therefore, special tuning of the photocatalyst like e.g. doping is needed to shift the band gap into visible light which after all makes it possible to sustainably obtain clean hydrogen from water splitting using sunlight.


Another approach is instead of cleaving bonds to deconstruct water or pollutants to use the potential of photocatalysts for bond formation organic synthesis.
