The development of highly active non‐noble metal catalysts for the oxygen reduction reaction (ORR) is important for commercialization of green energy conversion devices. A N‐doped carbon aerogel prepared by supercritical deposition of Co into an organic aerogel followed by pyrolysis in ammonia is shown to be an excellent catalyst for the ORR.
