Properties of Platinum Sub-Nanoclusters on Graphene Nano Sheets at Cathode
Abstract: The catalytic
activities of Pt subnano-clusters on graphene nanosheets (GNS) for oxygen
reduction reaction (ORR) catalysts have been examined. The ORR activity of Pt
on GNS (0.99 V) is higher than on carbon black (CB) commercial catalyst (0.94 V
versus RHE). A core level shift of Pt 4f in XPS indicates that Pt is chemically
interacted with GNS. It has been ascribed to difference in the interface
interaction between Pt and graphene via different strength of the π–d
hybridization.
