Abstract

Official abstract text for this publication.

One aspect of the present invention relates to a porous carbon material having a nitrogen content of 0.6 to 2.0% by mass, a G band half-value width of 51 to 60 cm−1 and an R value of 1.08 to 1.40 measured in a Raman spectrum using a laser having a wavelength of 532 nm, and iodine adsorption performance of 1000 to 1500 mg/g.

First claim

Opening claim text (preview).

The invention claimed is: 1. A porous carbon material comprising: a nitrogen content of 0.6 to 2.0% by mass; a G band half-value width of 51 to 60 cm −1 and an R value of 1.08 to 1.40 measured in a Raman spectrum using a laser having a wavelength of 532 nm; and iodine adsorption performance of 1000 to 1500 mg/g. 2. A molded body comprising the porous carbon material according to claim 1 . 3. A decomposition catalyst comprising the porous carbon material according to claim 1 . 4. The decomposition catalyst according to claim 3 , wherein the decomposition catalyst decomposes chloramine. 5. A method for producing the porous carbon material according to claim 1 , the method comprising: carbonizing a carbonaceous material to produce a carbonized product; activating the carbonized product at a temperature of 800 to 900° C.; and then activating the carbonized product further at a temperature of 900 to 980° C. 6. The method according to claim 5 , wherein the carbonaceous material is made of a natural mineral raw material. 7. The method according to claim 6 , wherein the natural mineral raw material has a nitrogen content of 1.0 to 2.0% by mass. 8. A method for decomposing and removing chloramine from an object, the method comprising contacting the object with a decomposition catalyst comprising the porous carbon material according to claim 1 . 9. A decomposition catalyst device comprising the molded body according to claim 2 . 10. A decomposition catalyst device comprising the decomposition catalyst according to claim 3 .
