None:
An uneven Co-N-C layer coated on electrochemically-exfoliated graphene as an active support (E1/2 0.788 V) to stabilize low-amount Pt catalyst was synthesized. The catalyst exhibited superior oxygen reduction activity (0.72 A mgPt-1) and durability (10 mV loss after 50k cycles) in acid. Graphene reinforced the metal-support interaction, benefitting the conductivity, activity and durability of the catalyst.
