Graphite Powder - an overview | ScienceDirect Topics

6.2.3 Graphite and Graphite Nanofiber. Bulky graphite powder adsorbed almost negligible amount of hydrogen, i.e., 0.037 wt% at 60 bar and 298 K [14], because of its stable and inaccessible structures for hydrogen. To improve the hydrogen storage in graphite, two common approaches, ball-milling and intercalation, are employed.

Graphite intercalation compound - Wikipedia

One of the best studied graphite intercalation compounds, KC 8, is prepared by melting potassium over graphite powder. The potassium is absorbed into the graphite and the material changes color from black to bronze. The resulting solid is pyrophoric. The composition is explained by assuming that the potassium to potassium distance is twice the distance between hexagons in the carbon framework.
