Room-Temperature Calcium Intercalation into Graphite Catalyzed by Sodium
Akira Iyo, Shigeyuki Ishida, Hiroshi Eisaki +2
Calcium (Ca) insertion into graphite (C) has been considered to require elevated temperatures, and its occurrence at room temperature (RT) has been regarded as highly unlikely. Her…

Accelerated Lanthanide Intercalation into Graphite Catalyzed by Na
Akira Iyo, Hiroshi Fujihisa, Yoshito Gotoh +4
Lanthanides () are notoriously difficult to intercalate into graphite. We investigated the possibility of using Na to catalyze the formation of -intercalated graphite and s…
