Dr. Shaojun Guo, Sen Zhang, Liheng Wu and Prof. Shouheng Sun Co/CoO Nanoparticles Assembled on Graphene for Electrochemical Reduction of Oxygen Angewandte Chemie International Edition 51
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).
