dc.description.abstract
Co-doping of Li/MgO, a well-known catalyst for the oxidative coupling of
methane, was investigated. It is demonstrated that Gd3+ and Fe3+ can be used
as spin sensors in these solids to investigate the structure via EPR
spectroscopy. These aliovalent ions occupy Mg2+ sites in the lattice; the
expected coupling with charge-compensating neighboring Li+ was detected. A
strong increase of the activity was observed. However, all samples suffered
from deactivation. The solubility of Gd3+ in MgO turned out to be inhibited.
No such restriction was observed for Fe3+.
