Conclusions
-
1.
The CO adsorbed on CoO-MgO solid solutions with high specific surface areas is bound to three different types of surface centers. The first type is a pair of Co2+ ions, one in octahedral coordination and one in square pyramidal coordination, each weakly interacting with neighboring ions. The second type of center is an individual Co2+ ion in square pyramidal coordination and strongly interacting with neighboring Co2+ ions in the same coordination. The third type of center is a variant of the second, one ion Co2+ ion in square pyramidal coordination interacting with neighboring Co2+ ions in octahedral coordination.
-
2.
The CO molecule bonds more firmly to centers of the first type than to centers of either of the other types.
