| 中文摘要 | a facile method to synthesize layered manganese oxide nanosheets was developed for the first time by using graphene oxide as a template. the in situ replacement of carbon atoms on the graphene oxide framework by edge-shared [mno6] octahedra provides a new methodology to synthesize graphene-based two-dimensional nanomaterials. the transformation of graphene oxide into delta-type mno2 nanosheets results in an especially high surface area (157 m(2) g(-1)), which is the highest value amongst today's mno2 nanomaterials. moreover, the mno2 nanosheets demonstrated prominent capacitance (similar to 1017 f g(-1) at a scan rate of 3 mv s(-1), and similar to 1183 f g(-1) at a current density of 5 a g(-1)) and remarkable rate capability (similar to 244 f g(-1) at a high scan rate of 50 mv s(-1) and similar to 559 f g(-1) at a high current density of 25 a g(-1)), indicating their promise in high energy and power density pseudosupercapacitors. |
