Metal carbide/carbon composite body having porous structure by three-dimensional connection of core-shell unit particles, preparation method thereof, and use of the composite body |
摘要 |
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. |

1. A metal carbide/carbon composite body which is formed by high-temperature calcination of a metal oxalate hydrate body having a certain shape 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. |
