Research focus

  • Heterogeneously photocatalyzed CO2 reduction in the aqueous phase
  • Synthesis of semiconducting photocatalysts based on graphitic carbon nitrides (g-C3N4) for the reduction of CO2 to C1 and C1+-products
  • Influence of reaction conditions and reactor types on product formation rates and the product composition

New concepts of integrative bioeconomy: Sustainable value creation through CO2 upgrading with sunlight (funded by ESF)

This ESF-funded project examines a number of different aspects of photocatalytic CO2 reduction in the aqueous phase. Firstly, various semiconductor photocatalysts based on graphitic carbon nitrides (g-C3N4) will be synthesized and evaluated with regard to the formation rate of C1- and C1+-products. The focus is placed on the influence of the illumination. In order to reach this aim, a sunlight simulator is used to enable a variation of the emitted light spectrum and intensity as well as realistic conditions. Subsequently, the influence of the reactor concept with emphasis on a comparison of batch and continuous-flow operation as well as catalyst arrangement in a fixed-bed or in suspension will be determined. The concepts examined here represent a reaction engineering approach to sustainable material value creation based on the chemical conversion of CO2 as a renewable resource.
