Uneven Co–N–C-coated graphene as a durable support for low-loading Pt oxygen reduction catalyst
An uneven Co-N-C layer coated on electrochemically-exfoliated graphene as an active support (<i>E</i><sub>1/2</sub> 0.788 V) to stabilize low-amount Pt catalyst was synthesized. The catalyst exhibited superior oxygen reduction activity (0.72 A mg<sub>Pt</sub><sup>-1</sup>) 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.
