Rapidly reducing graphene oxide

Nanomaterials The reduction of exfoliated graphene oxide platelets can produce graphene for applications in materials, energy storage, and catalysis. However, reduction methods often leave a substantial fraction of oxygenated functional groups in graphene, lowering its electrical conductivity. Voiry et al. report that brief microwave pulses (1 to 2 s) resulted in the near-complete reduction of graphene oxide. The resultant high-quality graphene, with high carrier mobility, served as a catalyst support with low overpotential for the oxygen reduction reaction. Science , this issue p.
