Abstract

A porous carbon material which is a single porous carbon material having micropores, mesopores and macropores, wherein, with respect to a total pore volume, the volume percentage of the micropores is 13 to 74 volume %, the volume percentage of the mesopores is 13 to 75 volumes, and the volume percentage of the macropores is 5 to 74 volume %.

Claims (22)

1 . A porous carbon material which is a single porous carbon material having micropores, mesopores and macropores,

wherein, with respect to a total pore volume, a volume percentage of the micropores is 13 to 74 volume %, a volume percentage of the mesopores is 13 to 75 volume %, and a volume percentage of the macropores is 5 to 74 volume %,

wherein the porous carbon material includes agglomerates or aggregates containing a plurality of particles having a crystalline structure or a polyhedral structure, and

wherein the particles have an average particle size of 2 nm to 500 nm.

2 . The porous carbon material according to claim 1 ,

wherein a volume ratio represented by [volume of macropores]/[volume of mesopores] is 1.1 to 4.0.

3 . The porous carbon material according to claim 1 ,

wherein a volume ratio represented by [volume of macropores]/[volume of micropores+volume of mesopores] is 0.14 to 1.5.

4 . A composite material comprising the porous carbon material according to claim 1 , and at least one selected from the group consisting of metals and metal oxides,

wherein the at least one selected from the group consisting of metals and metal oxides is supported on the porous carbon material.

5 . A composite material comprising the porous carbon material according to claim 1 and an organic substance,

wherein the organic substance is supported on the porous carbon material.

6 . A composite material comprising a porous carbon material and a metal-organic framework,

wherein the porous carbon material is a single porous carbon material having micropores, mesopores and macropores,

wherein the metal-organic framework is supported on the porous carbon material.

7 . A method for producing the porous carbon material according to claim 1 , comprising

a step of firing a metal-organic framework or a mixture containing a metal-organic framework and other substances.

8 . A functional material comprising the porous carbon material according to claim 1 , or

a composite material comprising the porous carbon material according to claim 1 and a metal-organic framework,

wherein the metal-organic framework is supported on the porous carbon material.

9 . The functional material according to claim 8 , which is an electrode material, a separation material, a sensor material, a spacer material, a reinforcing material, a gas adsorbent, a liquid adsorbent, an ion adsorbent, or a solid adsorbent.
