Nitrogen. The Rice group reported that the reactions of di nitrogen wi th ni obi urn and cobalt c usters( lc) exhibit reactivity patterns very similar to di hydrogen. Iron has not yet been observed to react in the gas phase with di nitrogen. The Rice group did report some... 

The combination of cobalt with other metals like Pd increases the synthetic utility of this methodology. Thus, a concurrent tandem catalysis reaction of 102 and 103 using first an homogeneous chiral palladium complex, followed by the action of heterogeneous cobalt/C led to high enantioselective synthesis of PK products 104 (Scheme 30) [129].

As is the case, for instance, in cobalt C-LiCo02 elements, an excessive discharge leads to the oversaturation of the LCO, which decomposes to produce hthium oxide Li20 and cobalt oxide CoO.
