Enhanced catalytic activity of nanoshell carbon co-doped with boron and nitrogen in the oxygen reduction reaction Takafumi Ishii, Takuya Maie, Naofumi Kimura, Yuki Kobori, Yasuo Imashiro and Jun-ichi Ozaki Article The use of carbon cathode catalysts in polymer electrolyte fuel cells instead of the current platinum catalysts is attracting increasing attention. We claim that two factors are important for enhancing the activity of carbon cathode catalysts in the oxygen reduction reaction (ORR): the formation of a nanoshell structure and co-doping with boron and nitrogen. Herein, we investigate th...続きを読む »

Synergistically enhanced oxygen reduction activity of iron-based nanoshell carbons by copper incorporation Takafumi Ishii, Takuya Maie, Mikiya Hamano, Takeaki Kishimoto, Mayumi Mizushiri, Yasuo Imashiro and Jun-ichi Ozaki Article Abstract This study reports the synergistic improvement of the oxygen reduction reaction (ORR) activity of a carbon catalyst prepared from a phenol–formaldehyde resin by simultaneous incorporation of Cu and Fe phthalocyanines. This carbon catalyst exhibited higher ORR activities than those prepared with either Cu or Fe phthalocyanines, with an approx. 28-fold maximum ...続きを読む »
