Rational Design of Transition Metal Complexes for the Catalytic Hydrogenation of Carbon Dioxide – A Synthetic, Spectroscopic and Quantum Theoretical Approach

  • Investigation of iron, cobalt, and nickel complexes as catalysts in the reduction of carbon dioxide by hydrogen
  • Spectroscopic characterization of reactive intermediates
  • Quantum theoretical determination of the electronic properties, reaction barriers, and rate-determining steps
  • Investigation of the influence of the ligand architecture on the reaction barriers to determine a structure/reactivity relationship
  • Development of other more efficient catalysts based on the results obtained
