Green synthesis of Pt/CeO2/graphene hybrid nanomaterials with remarkably enhanced electrocatalytic properties

We developed a facile strategy for clean synthesis of Pt/CeO(2)/graphene nanomaterials with remarkably enhanced catalytic properties. The graphene oxide (GO) could be used as an oxidant to oxidize Ce(3+) into CeO(2) NPs, and l-lysine was used as a linker to realize the in situ growth of Pt NPs around CeO(2) NPs dispersed on graphene.
