Abstract
The present invention relates to a metal carbide/carbon composite body having a porous structure, in which core-shell unit particles are three-dimensionally connected, a preparation method thereof, and the use of the composite body. More specifically, the present invention provides a metal carbide/carbon composite body, a preparation method thereof, and the use of the composite body, wherein the composite body is formed by high-temperature calcination of a metal oxalate hydrate body under a carbon monoxide-containing gas atmosphere, wherein the metal carbide/carbon composite body has a porous structure in which core-shell unit particles are three-dimensionally connected, wherein the core-shell unit particles comprise a metal carbide core formed by thermal decomposition of a metal oxalate hydrate; and a graphitic carbon shell, the product resulting from Boudouard reaction of carbon monoxide, formed on the metal carbide core.
