PROBLEM TO BE SOLVED: To easily control the nitrogen content of a nitrogen-contg. carbon material by carbonizing a nitrogen-contg. thermosetting resin after hardening. SOLUTION: A nitrogen-contg. thermosetting resin such as melamine resin, urea resin, aniline resin, bismaleimide resin or benzoxazine resin is blended with a nitrogen-free carbon precursor and/or a nitrogen-free carbon material such as pitch, coke, cellulose, PVC resin, wood, sugar, furan resin, cellulose acetate, epoxy resin, butadiene rubber or phenolic resin and the blend is hardened and carbonized in an atmosphere of an inert gas or CO to obtain the objective nitrogen-contg. carbon material having 1-50 wt.% nitrogen content. The nitrogen-contg. carbon material having an arbitrary nitrogen content is easily prepd. in high yield without using a special apparatus. The nitrogen content of the nitrogen-contg. carbon material can be controlled in accordance with carbonization temp. and time. |
