Outline of Final Research Achievements

Changes in chemical and structural properties of a phenolic resin after nitrogen-ion implantation and subsequent carbonization were investigated in order to develop synthesis process of a nitrogen-containing carbon alloy with catalytic activity. It was found that (1) nitrogen was incorporated into molecules in the phenolic resin forming C-N bonds, (2) the implanted nitrogen was remained after the carbonization to form turbostratic graphite-structure including pyridinic nitrogen, and (3) obtained carbon material showed oxygen reduction reaction (ORR) potential of 0.7 V vs RHE. According to these results, it was demonstrated that ion implantation technique is effective to synthesize a nitrogen-containing carbon alloy from a precursor polymer.
