Catalysis and membrane technology

Lupe

Catalysis is utilized for the preparation for the majority of chemical products. Because it leads to less energy consumption and waste, catalysis is one of the main topics in green chemistry. We develop catalyst materials mainly for the oxidative coupling of methane, oxidative dehydrogenation of propane, dry-reforming of methane, activation of CO2 and CH4 as well as for photocatalytic water. Furthermore, we focus on the development of ceramic membranes for gas separation, high temperature catalysis and catalytic membrane reactors.

Topics

  • tailoring of catalyst support
  • up-scaling of the synthesis and processing of catalytic materials
  • high temperature stable catalysts
  • charge transport in catalysis
  • ceramic membranes for gas separation and membrane reactors

Financial Support / Projects

  • UniCat (Cluster of Excellence “Unifying Concepts in Catalysis)
  • BIG-NSE (Berlin International Gracutate School of Natural Sciences and Engineering)
  • Else-Neumann-Stipendium des Landes Berlin
