| Outline of Final Research Achievements |
A novel process for fabricating a nitrogen-doped carbon catalyst from a precursor polymer utilizing the high-energy electron beam (EB) irradiation technique was examined with the aim of simultaneously forming a graphitic nanostructure and nitrogen doping in thermally non-equilibrium conditions. A blend of phenolic resin and cobalt chloride was irradiated by a 2 MeV EB under flowing ammonia gas and heated up to 800 °C. It was found that the EB irradiation produces carbon material with a high content of the graphite phase and enhances the amount of N-doping, especially pyridinic-N, compared with the common heat treatment in an electric furnace. The obtained carbon material exhibited catalytic activity for oxygen reduction reaction (ORR) with an ORR potential of 0.7 V versus RHE and an electron transfer number of 3 in 0.5 M H2SO4.

| Academic Significance and Societal Importance of the Research Achievements |
化学プラントや自動車の排ガス浄化、燃料電池等の発電デバイスには白金触媒が必要不可欠であるが、現在確認されている埋蔵量では将来の需要を満たせないため、同等の触媒性を有する非半金で安価な触媒材料が不可欠である。この材料は、高分子材料を、高温で炭素化し作製するもので、同等の触媒性能が発現すれば、自動車やガス給湯と組み合わせた家庭用発電装置などとして、生活の身近な部分にも幅広く活用が期待できるものである。
