摘要:

通过两步溶剂热法制备得到三维氮掺杂石墨烯与吡啶氧基钴酞菁的复合材料(CoTPPc/NGA). 该复合材料具有优良的氧气还原性能, 在起峰电位和半波上接近商业化的铂碳催化剂(Pt/C), 且在稳定性和抗甲醇性能上优于铂碳催化剂, 有望代替铂碳催化剂成为碱性直接甲醇燃料电池的阴极催化剂.

Abstract:

A two-step solvothermal approach for the synthesis of three-dimensional(3D) N-doped graphene aerogel and cobalt tetrapyridyloxyphthalocyanine composite(CoTPPc/NGA) as a novel and efficient non-precious catalyst in the oxygen reduction reaction(ORR) was reported. The resulted hybird exhibited impressive ORR catalytic activity and superior stability as well as excellent methanol crossover to commercial Pt/C, which could be used as an alternative Pt-free catalyst in alkaline direct methanol fuel cells(DMFCs).

Key words: N-Doped graphene, Aerogel, Cobalt phthalocyanine, Oxygen reduction reaction
