Zusammenfassung:
Graphene oxide-intercalated alpha-metal hydroxides were prepared using
layers from the delaminated colloidal dispersions of
cetyltrimethylammonium-intercalated graphene oxide and
dodecylsulfate-intercalated alpha-hydroxide of nickel/cobalt as
precursors. The reaction of the two dispersions leads to
de-intercalation of the interlayer ions from both the layered solids and
the intercalation of the negatively charged graphene oxide sheets
between the positively charged layers of the alpha-hydroxide. Thermal
decomposition of the intercalated solids yields graphene/nanocrystalline
metal oxide composites. Electron microscopy analysis of the composites
indicates that the nanoparticles are intercalated between graphene
layers. (C) 2010 Elsevier Ltd. All rights reserved.
