摘要： 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.

摘要： The present disclosure relates to a metal nanoparticles impregnated activated carbon fiber for removing harmful substances, and a method of manufacturing the same. A method of manufacturing a metal nanoparticles impregnated activated carbon fiber for removing harmful substances according to the present disclosure includes an activation step of manufacturing an activated carbon fiber by heat-treating a precursor including a waste carbon fiber under a mixed atmosphere of activation gases including water vapor, carbon monoxide, nitrogen, argon, helium, or combinations thereof, and a metal containing step of containing metal in the activated carbon fiber. According to the present disclosure, a carbonization process is unnecessary since a precursor including the waste carbon fiber is used, and the metal nanoparticles impregnated activated carbon fiber may have remarkably improved adsorptive power compared to an activated carbon fiber with the same specific surface area by controlling the micropore distribution.

摘要： A range of carbon materials can be produced using lignin in combination with synthetic phenolic resins or naturally occurring lingo-cellulosic materials. The lignin, which is essentially a naturally occurring phenolic resin, has a carbon yield on pyrolysis similar to that of the synthetic resins, which aids processing. The lignin can be used as a binder phase for synthetic resin or lignocellulosic materials allowing the production of monolithic carbons from a wide range of precursors, as the primary structural material where the thermal processing is modified by the addition of small quantities of synthetic resin materials or as structure modified in the production of meso/macro porous carbons in either bead, granular or monolithic form. A carbonised monolith is provided comprising mesoporous and/or macroporous carbon particles dispersed in a matrix of microporous carbon particles with voids between the particles defining paths for fluid to flow into and through the structure. The monolith may take the form of a shaped body having walls defining a multiplicity of internal transport channels for fluid flow, the transport channels being directed along the extrusion direction. The monolith may be made by carbonising a shaped phenolic body based on phenolic resin precursors. In a method for producing such a carbonisable shaped resin body solid particles of a first phenolic resin are provided which is partially cured so that the particles are sinterable but do not melt on carbonisation. The particles of the first phenolic resin are mixed with particles of a second phenolic resin that has a greater degree of cure than said first phenolic resin and has a mesoporous and/or macroporous microstructure that is preserved on carbonisation. The resulting mixture is formed into a dough e.g. by mixing the resin particles with methyl cellulose, PEO and water, after which the dough is extruded to form a shaped product and stabilising in its shape by sintering.

摘要： A molecular species is covalently attached to elemental carbon by exposing the carbon to a reaction mixture containing a strong base and a compound of the formula or in which X denotes a covalently attached atom or group capable of forming an X− anion and each Z is a moiety comprising a plurality of atoms, but which does not have a hydrogen atom directly attached to the atom which itself is directly attached to the —CH2X or —CHX group. The carbon substrate may be graphite or carbon nanotubes.
