Abstract

Official abstract text for this publication.

The present invention relates to a porous carbon material having a nitrogen content of 0.5 to 2.0 mass % and an iron content of at least 400 mg/kg-porous carbon material or more, and also having an electrical conductivity of 10 S/cm or more as determined by powder resistance measurement.

First claim

Opening claim text (preview).

The invention claimed is: 1. A porous carbon material having a nitrogen content of 0.5 to 2.0 mass % and an iron content of at least 400 mg/kg-porous carbon material or more, and having an electrical conductivity of 10 S/cm or more as determined by powder resistance measurement. 2. The porous carbon material according to claim 1 , wherein benzene adsorption performance is in a range of 25 to 50%. 3. A molded body, comprising the porous carbon material according to claim 1 . 4. A decomposition catalyst device comprising the molded body according to claim 3 . 5. A decomposition catalyst comprising the porous carbon material according to claim 1 . 6. A decomposition catalyst device comprising the decomposition catalyst according to claim 5 . 7. The decomposition catalyst according to claim 5 , which is a decomposition catalyst for at least one of a peroxide, chloramine, and bromic acid. 8. A method for producing the porous carbon material according to claim 1 , the method comprising: carbonizing a carbonaceous material to produce a carbonized product, heat-treating the carbonized product at a temperature of 1000 to 1200° C., and activating a heat-treated product at a temperature of 850 to 1000° C. in a mixed gas atmosphere comprising water vapor, nitrogen, and carbon dioxide. 9. The method according to claim 8 , wherein the carbonaceous material derives from a natural mineral raw material. 10. The method according to claim 9 , wherein the natural mineral raw material has a nitrogen content of 1.0 to 2.0 mass %. 11. A method for decomposing and removing at least one of a peroxide, chloramine, bromic acid, hypobromous acid, and hypochlorous acid from an object, the method comprising: contacting the porous carbon material according to claim 1 as a decomposition catalyst with the object.
