Abstract
This invention provides a process for preparing a reactive graphite-like layered material with high chemical reactivity while maintaining stability of a base material. In the preparation process according to this invention, first, the treatment for reducing the number of dangling bonds in the vicinity of the vacancy to form an introducing site is conducted by binding atoms together with each other, which atoms are adjacent to a vacancy in a graphite-like layered material. Then, atoms 3 and 4 to be introduced, i.e., a diatomic molecule made of atoms constituting the graphite-like layered material are introduced into the introducing site formed in advance. Then, new bonds are generated between introduced atoms 3, 4 and the graphite-like layered material.

A process for preparing a reactive graphite-like layered material, which is 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.
