✦ Synopsis

A hybrid graphene/Ni 2+ -Fe 3+ layered double hydroxide material has been fabricated by the hydrothermal treatment of a mixed suspension of the exfoliated graphite oxide, Ni(NO 3 ) 2 6H 2 O, Fe(NO 3 ) 3 AE9H 2 O, urea and trisodium citrate. The Ni 2+ -Fe 3+ layered double hydroxide platelets are first homogeneously grown on the surface of GO nanosheets which are then reduced to graphene under a mild hydrothermal treatment. In the hybrid graphene/Ni 2+ -Fe 3+ layered double hydroxide material, the restacking of graphene nanosheets is effectively prevented by the formation of Ni 2+ -Fe 3+ layered double hydroxide platelets, and the graphene nanosheets exist in a complete exfoliation state.
