WP3: Synthesis of TiO2-Reduced Graphene Oxide (RGO) composite photocatalysts

  • Synthesis of TiO2-reduced graphene oxide composite photocatalysts and optimization of important preparation conditions.
  • Application of three different methodologies for the reduction of graphene oxide (GO) and the simultaneous formation of TiO2-RGO   composite catalysts:
  • Photocatalytic method: GO will be reduced photocatalytically by TiO2with the simultaneous formation of TiO2-RGO composites
  • Hydrothermal method: GO will be reduced hydrothermally in the presence of TiO2
  • Microwave method: GO will be reduced by microwave irradiation in the presence of TiO2.

WP4: Characterization of the synthesized photocatalysts and toxicity measurements

  • Determination of the concentrations at which the synthesized catalysts are toxic to our test organisms.
  • Determination whether initial concentration of test organisms plays important role concerning toxicity effects.
  • Assessment of chronic toxicity based on the acute toxicity results
