Objective

To use free-cluster approaches to study elementary reaction processes on model systems

Tasks
Task 4.1. Free cluster catalysis tests
  • Production of free metal-oxide clusters (Cu,Zn, Au, Pd) with exactly controlled elementary composition and charge state
  • Investigation of their reactive properties (UU)
Task 4.2. Free clusters and reaction intermediates structural characterisation
  • Structural characterization of free metal oxide clusters by using IR spectroscopy
  • Production of free bimetallic CuZn and NiGa clusters and investigation of their adsorption properties by using IR spectroscopy
  • Investigation of the catalytic activity of these clusters in an ion trap (UU)
Task 4.3. Free clusters active sites
  • Identification of important reaction intermediates and active centers of free Cu- and Ni-based clusters by ion trap mass spectrometry and DFT calculations
