Abstract

image

The development of highly-active bifunctional catalysts at low cost for both oxygen reduction and oxygen evolution reactions are greatly required for fuel cells, metal–air batteries, and water splitting. As reported by Q. Zhang, F. Wei, and co-workers on page 2251, nitrogen-doped graphene/single-walled carbon nanotube hybrids exhibit very high activity for both the oxygen reduction reaction and oxygen evolution reaction, which opens up new avenues for energy conversion technologies based on earth-abundant, scalable, precious-metal-free catalysts.
