Abstract:
Reactive units and intermediates that are
relevant on the surfaces of vanadiumoxide-based catalysts during oxygenation
/ dehydrogenation of organic substrates are to be modelled in their structures
and functions.
For simulating the oxo-surfaces two different types of potential ligands will
be used: calixarenes and silsequioxanes.
As a result insight in reaction mechanisms and information about the characteristics
of the catalysts mentioned above are expected.
Furthermore, simple, non-ligated oxovanadium-aggregates are being matrixisolated,
characterized by vibrational spectroscopy and tested for their reactivity towards
organic substrates.
