Bifunctional Carbon Catalysts Intercalates

Bifunctional Carbon Catalysts Intercalates. - Although it is not the purpose of this article to consider carbon as a support, there are several examples of bifunctionality in supported carbon catalysts. In some way the graphite intercalate catalysts considered later in this Section can be described in these terms. 

Graphite or carbon, as a support, can induce different properties in a catalyst by, for example, promoting spill-over or affecting catalyst geometry. At the same time, however, graphite (in particular) can act as an electron transfer agent and, as a result, become involved in reaction as a co-catalyst. This electron transfer role has been noted previously in connection with cases where carbon itself is the main catalyst. As a co-catalyst with another material, the electron transfer properties of carbons have been suggested to be important in a variety of reactions. 

Aika et found that a combination of ruthenium, alkali metal, 

Graphite intercalate compounds are among the best known carbonaceous catalysts, and there is good evidence that electron transfer is important in these systems. The systems were reviewed by Boersma in 1974 and attention will be focused on a few important papers before and after then.
