Abstract

The present invention relates to a porous carbon material having a co-continuous structure forming portion in which carbon skeletons and voids form continuous structures, respectively and which has a structural period of 0.002 μm to 3 μm, having pores which have an average diameter of 0.01 to 10 nm on a surface thereof, and having a BET specific surface area of 100 m 2 /g or more.

First claim

1 . A porous carbon material having a co-continuous structure portion in which carbon skeletons and voids form continuous structures, respectively and which has a structural period of 0.002 μm to 3 μm, having pores which have an average diameter of 0.01 to 10 nm on a surface thereof, and having a BET specific surface area of 100 m 2 /g or more.

2 . The porous carbon material according to claim 1 , wherein the pores are formed at least on the carbon skeletons of the co-continuous structure portion.

3 . The porous carbon material according to claim 1 , wherein a pore volume measured by an MP method is 0.1 cm 3 /g or more.

4 . The porous carbon material according to claim 1 , wherein the BET specific surface area is 1,000 m 2 /g or more.

5 . The porous carbon material according to claim 1 , having a portion having substantially no co-continuous structure.

6 . An electrode material using the porous carbon material according to claim 1 .

7 . An adsorption material using the porous carbon material according to claim 1 .

8 . A process for producing a porous carbon material, the process comprising:
step 1: a step of bringing 10 to 90% by weight of a carbonizable resin and 90 to 10% by weight of an eliminable resin into a compatibly mixed state to obtain a resin mixture; step 2: a step of causing the resin mixture to undergo phase separation by a method not accompanied with a chemical reaction, and fixing the separated phases; step 3: a step of performing carbonization by pyrolysis; and step 4: a step of activation,
in this order.

9 . The process for producing a porous carbon material according to claim 8 , wherein an infusibilizing treatment is further performed after the step 2.

10 . The process for producing a porous carbon material according to claim 8 , wherein, in the step 4, the activation is performed with an alkaline chemical.

11 . The process for producing a porous carbon material according to claim 8 , wherein a pulverization treatment is further performed after the step 3 and before or after the step 4.
