Fabrication of a hybrid graphene/layered double hydroxide material

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 2O, Fe(NO 3) 3·9H 2O, urea and trisodium citrate. The Ni 2+–Fe 3+ layered double hydroxide platelets are first homog...

Summary: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 2O, Fe(NO 3) 3·9H 2O, 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.
