Porous carbon and method of manufacturing same

A porous carbon comprising:

• mesopores,
• a carbonaceous wall constituting an outer wall of the mesopores, the carbonaceous wall forming a mesh three-dimensional network structure, and
• micropores,
• wherein the micropores are each formed in a position facing the mesopores in the carbonaceous wall, wherein a peak is present at a Bragg angle 2θ of 26.45° in an X-ray diffraction spectrum to a CuKα ray (wavelength 1.541 angstroms) of the carbonaceous wall, and
• wherein the porous carbon consists of carbon.

A method of manufacturing a porous carbon consisting of carbon, the porous carbon having a three-dimensional network structure, wherein

• a noncrystalline carbonaceous carbonized body having mesopores is manufactured by the steps of:
• mixing a flowable material containing an organic resin with template particles comprising at least one alkaline-earth metal compound selected from the group consisting of an oxide, a hydroxide, a carbonate and an organic acid salt of an alkaline-earth metal, to prepare a mixture;
• carbonizing the mixture in a non-oxidizing atmosphere to prepare a carbonized substance;
• and removing the template particles in the carbonized substance to obtain the noncrystalline carbonaceous carbonized body having mesopores, wherein the carbon yield of the flowable material is from 40% to 85%,
• the noncrystalline carbonaceous carbonized body having mesopores is subjected to a crystallization treatment to heat a target in a non-oxidizing atmosphere or a reduced-pressure atmosphere at a temperature equal to or higher than a temperature at which the noncrystalline carbonaceous carbonized body having mesopores is crystallized, thereby obtaining the porous carbon comprising:
• the mesopores;
• a carbonaceous wall constituting an outer wall of the mesopores, the carbonaceous wall forming the three-dimensional network structure, the carbonaceous wall having a portion forming a layered structure;
• and micropores each formed in a position facing the mesopores in the carbonaceous wall.

A porous carbon comprising:

• micropores,
• wherein the micropores are each formed in a position facing the mesopores in the carbonaceous wall,
• wherein the carbonaceous wall has a portion being graphitized,
• wherein the porous carbon consists of carbon, and
• wherein the capacity of the micropores is 0.12 ml/g or more.
