▎ 摘　　要

A hybrid graphene/Ni2+-Fe3+ layered double hydroxide material has been fabricated by the hydrothermal treatment of a mixed suspension of the exfoliated graphite oxide, Ni(NO3)(2) 6H(2)O, Fe(NO3)(3)center dot 9H(2)O, urea and trisodium citrate. The Ni2+-Fe3+ 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/Ni2+-Fe3+ layered double hydroxide material, the restacking of graphene nanosheets is effectively prevented by the formation of Ni2+-Fe3+ layered double hydroxide platelets, and the graphene nanosheets exist in a complete exfoliation state.
