Microporous carbon material, manufacturing method thereof, and hydrogen storage method using microporous carbon material

摘要

The present invention provides a microporous carbon material capable of expressing functions that supported metal has while maintaining pore functions that the microporous carbon material inherently possesses. The microporous carbon material 5 includes: a three-dimensional long-range ordered structure within a range from 0.7 nm or more to 2 nm or less; and micropores 2a, wherein a transition metal 4 is supported on surfaces of the micropores 2a. The microporous carbon material is obtained by a method including: introducing an organic compound on a surface of and inside the micropores of a porous material containing transition metal, and obtaining a composite of the microporous carbon material containing the transition metal and the porous material by carbonizing the organic compound by a chemical vapor deposition method; and removing the porous material. Alternatively, the microporous carbon material is obtained by a method including: introducing an organic compound on a surface of a porous material and obtaining a microporous carbon material by a chemical vapor deposition method; and supporting the transition metal on a surface of the microporous carbon material by immersing and impregnating the microporous carbon material in a transition metal salt solution.
