Abstract (click image for pdf file)

Pt hollow nanostructures assembled by nanocrystals were in situ grown and hung onto graphene layers to combine the merits from favorable catalyst morphology control and synergetic improvement effect of the graphene support, resulting in a composite with enhanced electrocatalytic performance.
