Carbon material and method for producing same

摘要

A porous carbon material having excellent graphite crystallinity, good carrier mobility and proper porosity, a porous carbon material having edges of carbon hexagonal planes located on outer surfaces of particle and structure, and flaky graphite being similar to graphene are produced.;By subjecting a carbon material, in which a closed-pore-ratio and an amount of remaining hydrogen in the material are set to be within a proper range, to hot isostatic pressing treatment, a vapor phase growth reaction of graphite is generated in closed pores as nuclei using hydrogen and hydrocarbon generated from the carbon material, thereby producing a large amount of targeted porous carbon material at low cost. Flaky graphite being similar to graphene is produced by applying physical impact to the obtained porous carbon material or by generating a graphite intercalation compound using the porous carbon material as a host and then quickly heating the compound.

1. A method for producing a porous carbon material, said method comprising:
pre-baking a molded polymer material for carbonization to produce a pre-baked article containing a given amount of remaining hydrogen and having a closed-pore-ratio of not less than 2%; and subjecting the pre-baked article to hot isostatic pressing treatment using a compressed gas atmosphere, to produce porous carbon material having edges of carbon hexagonal planes on an outer surface thereof.
