Abstract:
A porous carbon that has an extremely high specific surface area while being crystalline, and a method of manufacturing the porous carbon are provided.
A porous carbon has mesopores 4 and a carbonaceous wall 3 constituting an outer wall of the mesopores 4, wherein the carbonaceous wall 3 has a portion forming a layered structure. The porous carbon is fabricated by mixing a polyamic acid resin 1 as a carbon precursor with magnesium oxide 2 as template particles; heat-treating the mixture in a nitrogen atmosphere at 1000° C. for 1 hour to cause the polyamic acid resin to undergo heat decomposition; washing the resultant sample with a sulfuric acid solution at a concentration of 1 mol/L to dissolve MgO away; and heat-treating the noncrystalline porous carbon in a nitrogen atmosphere at 2500° C.
