Outline of Final Research Achievements

In general, metal oxide nanosheets have been prepared by exfoliation of layered metal oxides or metal hydroxides. Highly crystalized metal oxide nanosheets can be obtained by this exfoliation method, but types of metal oxide annosheets thus obtained are limited because the method requires the layered compounds as stating materials. In the present study, we have developed the preparation method of metal oxide nanosheets by using graphene as a template. We demonstrated that metal oxide nanosheets were formed from the corresponding metal alkoxides and graphene oxide.
