Preparation of metal oxide nanosheets has been one of the most interesting topics in the field of materials chemistry since the discovery of graphene. We developed a facile method for the preparation of metal oxide nanosheets using graphene oxides as templates. Metal oxide precursors such as metal alkoxides and metal chlorides are stabilized on the surface of graphene oxides because oxygen-containing functional groups on the surfaces of graphene oxides work as anchoring sites for the metal oxide precursors. The composites of metal oxide nanosheets and reduced graphene oxides can be obtained by the treatment of graphene oxide with metal oxide precursors at 453 K in the autoclave. Free-standing metal oxide nanosheets can be also prepared by the calcination of the metal oxide nanosheet-reduced graphehe oxide composites in air through the combustion of carbon atoms.
