Patent ID: 7632551

Claim:
A process for preparing a reactive graphite-like layered material, which is a mono- or multi-layered material having a hexagonal main framework with chemical reactivity, from a graphite-like layered material referring to a mono- or multi-layered material having a hexagonal main framework comprising the steps of: binding atoms having a dangling bond together with each other which are adjacent to a vacancy included in said graphite-like layered material, for reducing the number of dangling bonds in the vicinity of said vacancy to form an introducing site; introducing a molecule or atom constituting the graphite-like layered material into the introducing site; and generating a new bond between the introduced molecule or atom and the graphite-like layered material, wherein the vacancy included in said graphite-like layered material is formed in the shape of a diatomic vacancy or a monoatomic vacancy by detaching two adjacent atoms or one atom away from the graphite-like layered material, and wherein the molecule or atom to be introduced into the introducing site is generated by decomposition of ethylene or acetylene or plasma excitation of a mixed gas of nitrogen and HfB 2 , and the molecule or atom to be introduced into the introducing site is contacted with the graphite-like layered material for introduction.
