Melamine resin containing boron was synthesized from boric acid, melamine, and formaldehyde. B/C/N materials were prepared by carbonization in an inert gas atmosphere at 800-1200 °C. The boron/carbon atomic ratio (B/C) increased from 0.02 to 0.42 as a result of the formation of more B-N bonds with increasing heat treatment temperature, and it is the formation of these bonds that fixes the nitrogen in the structure. XPS measurements indicate that nitrogen atoms are involved in the following bonding states: B-N, pyridine-type N, quaternary-N and B-N-C. It is clear that B-N-C and B-N bonds are formed during carbonization at temperatures >800 °C, where the elimination of nitrogen is usually observed, and these are responsible for the N retention. As a result, a high N/C atomic ratio of 0.09-0.42 was observed for a carbonization temperature greater than 800 °C. The EDLC capacitance of a material heat treated at 1000 °C with N/C of 0.24 had a high value of 500 F·g-1 in spite of having a smaller specific surface area compared to that of activated carbon widely used in EDLC.
