In Situ/Operando Studies of Functional Materials

The group deals with structural aspects of various inorganic solids, which are used in energy-relevant processes either as storage material, catalyst carrier material or catalysts.

  • Complex metal hydrides for solid hydrogen storage or as solid electrolytes in batteries
  • Catalysts for the catalytic cracking of ammonia, NH3, into hydrogen and nitrogen for fuel cell applications
  • Perovskites as electrode material in fuel cells or for catalytic water splitting
  • Oxide catalysts
  • Carbon materials for battery applications
  • Inorganic, polymer-based catalyst supports
