Abstract: Disclosed is a carbon material, such as a carbon nanotube, into which a boron atom and/or a phosphorus atom is/are introduced while maintaining its characteristic structures and functions and a method for producing the same. The carbon material of the present invention is one in which a boron atom and/or a phosphorus atom is/are introduced into part of carbon atoms composing the carbon material, and can be produced by a method for producing a carbon material including the steps of: bringing a carbon material into contact with a fluorination treatment gas containing a fluorine-containing gas, thereby subjecting a surface of the carbon material to fluorination treatment; and bringing the carbon material after the fluorination treatment into contact with a boronization treatment gas containing a boron-containing gas, thereby subjecting to boronization treatment and/or into contact with a phosphorization treatment gas containing a phosphorus-containing gas, thereby subjecting to phosphorization treatment.

Abstract: The present invention is a surface-modified carbon material including chemical addends added to the surface of graphene, such that a one-dimensional periodicity corresponding to a large number of addition positions of the chemical addends can be observed in a Fourier-transformed image of a scanning probe microscopic image of the surface of graphene. The surface-modified carbon material of the present invention has a bandgap and therefore can be used as a sensor capable of electronically controlling an operation or another electronic device.

Abstract: Nanoporous carbon-based scaffolds or structures, and specifically carbon aerogels and their manufacture and use thereof. Embodiments include a cathode material within a lithium-air battery, where the cathode is formed of a binder-free, monolithic, polyimide-derived carbon aerogel. The carbon aerogel includes pores that improve the oxygen transport properties of electrolyte solution and improve the formation of lithium peroxide along the surface and/or within the pores of the carbon aerogel. The cathode and underlying carbon aerogel provide optimal properties for use within the lithium-air battery.
