▎ 摘　　要

NOVELTY - Metal-impregnated nano-carbon composite comprises a carbon body having pores, and a functional metal bonded to carbon fibers formed in the pores. USE - The nano-carbon composite is useful as gas adsorbent, and electromagnetic wave adsorbent (all claimed). ADVANTAGE - The nano-carbon composite has improved chemical adsorption capacity, electromagnetic wave shielding ability for a specific frequency, and desired pore shape, and is stable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for controlling shape of metal-impregnated nano-carbon composites comprising supporting a functional metal on the carbon body, heat-treating the carbon body on which the functional metal is supported, and simultaneously stabilizing the functional metal supported on the carbon body, and heat-treating the performed carbon body in a gas atmosphere containing carbonized gas, and growing fibrous carbon in the developed pores of the carbon body.
