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.

Abstract: To provide a novel immobilized product in which a carbon material and/or a silicon material is/are immobilized on a base material surface by a chemical bond via a linking group, and a method for producing the same. The immobilized product is an immobilized product in which a carbon material is immobilizing on a surface of a base material, wherein the carbon material is chemically bonded on the surface of the base material via a linking group, and the linking group is at least one selected from the group consisting of a —NH group, a —NH—R1—NH group, a —SO group, a R2 group, a —O—R3—O group, and a R4 group (in which the R1 to R4 each independently represent at least one selected from the group consisting of a chain alkyl group, a cyclic alkyl group, a chain alkenyl group, a cyclic alkenyl group, a chain alkynyl group, etc.).

Abstract: A cross-linked structure of a carbon material is excellent in mechanical strength, such as tensile strength. The carbon materials such as carbon nanotube, graphite, fullerene, and carbon nanocoil, are cross-linked with each other. The carbon materials are cross-linked through a linking group derived from a nucleophilic compound having two or more nucleophilic groups in the molecule.
