Abstract
A nitrogen-containing carbon material to the present invention comprises a carbon material having a carbon skeleton formed of carbon atoms and nitrogen atoms introduced into the carbon material, wherein part of carbon atoms in the carbon skeleton are substituted with nitrogen atoms. The nitrogen-containing carbon material according to the present invention can be produced by a production method including the steps of bringing the carbon material into contact with a first treatment gas containing a fluorine-containing gas to subject a surface of the carbon material to a fluorination treatment; and bringing the carbon material after being subjected to the fluorination treatment into contact with a second treatment gas containing a nitrogen-containing gas with heating to perform a nitriding treatment.
