Abstract:
An efficient and universal method to directly hybridize isocharged nanosheets of layered metal oxide and reduced graphene oxide (rGO) is developed on the basis of the surface modification and an electrostatically driven assembly process. On the basis of this synthetic method, the CoO2 -rGO nanocomposite can be synthesized with exfoliated CoO2 and rGO nanosheets, and transformed into CoO-CoO2 -rGO nanocomposites with excellent electrode performance for lithium-ion batteries. Also, this surface-modification assembly route is successfully applied for the synthesis of another mesoporous TiO2 -rGO nanocomposite. This result provides clear evidence for the usefulness of the present method as a universal way of hybridizing isocharged anionic nanosheets of inorganic solids and graphene.
