Technologies for Catalyst Synthesis

About

For the synthesis of sustainable chemicals, a catalyst must be used to lower the activation energy of the reactions so that they can proceed at lower temperatures with high conversions. Lower temperatures are advantageous because simpler and cheaper materials can be used in the technical implementation and because less energy must be introduced into the process from the outside. Catalysts usually consist of a catalyst support (pellets or powder) with the largest possible outer surface and an inner pore system, to which and in which the catalyst particles are finely distributed. In simplified terms, one can imagine that the starting materials of a reaction adsorb on the catalyst particles and react there to form the products, which then desorb from the particle surface again. The topics listed below are being addressed by this research group for the development of catalysts.

Research Topics

  • Wet-chemical synthesis (impregnation, deposition) of catalysts for the synthesis of higher alcohols from mixtures of green methanol and ethanol.
  • Wet-chemical synthesis of catalysts for the e-methanol-to-jet fuel reaction.
  • Development and patenting of a technology for the deposition of nanoparticles on powdered catalyst supports.
  • Venture building with the technology of depositing nanoparticles on different substrates
