摘要：

Good support: A solution-phase self-assembly approach leads to Co/CoO core/shell nanoparticles deposited on graphene (G-Co/CoO NPs). Their catalytic activity for the oxygen reduction reaction in O2-saturated KOH solution depends on the thickness of the CoO shell (green in picture). The optimized G-Co/CoO NPs have a comparative activity and better stability than the commercial Pt NP catalyst supported on carbon (C-Pt). Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
