The
performance of Co3Mo3N, Co3Mo3C, and Co6Mo6C for ammonia synthesis
has been compared. In contrast to Co3Mo3N, which
is active at 400 °C, a reaction temperature of 500 °C, which
was preceded by an induction period, was necessary for the establishment
of steady state activity for Co3Mo3C. Co6Mo6C was found to be inactive under the conditions
tested. During the induction period, nitridation of the Co3Mo3C lattice was found to occur, and this continued throughout
the period of steady state reaction with the material transforming
in composition toward Co3Mo3N. Taken together,
these observations demonstrate that ammonia synthesis activity in
ternary cobalt molybdenum systems is associated with the presence
of N in the 16c Wyckoff lattice site.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
