Abstract

A core-shell and spherical structured Fe O @MnO nanostructure is designed and developed via a facile and low-cost two-step 3 4 2 method. Core-shell structured Fe O @MnO with uniform morphology can be obtained after layered structured δ-MnO is 3 4 2 2 grown on the surface of Fe O nanospheres. The crystal structures and morphology of as-prepared Fe O @MnO are charac- 3 4 3 4 2 terized by scanning electron microscopy, X-ray diffraction, nitrogen isotherm analysis, and transmission electron microscopy. At −1 −1 the current density of 0.1 A g , the specific capacitance of Fe O @MnO is 243.7 F g , and its capacitance retention is almost 3 4 2 −1 100% after 3000 continuous charge/discharge cycles at current density of 1 A g . The excellent cycling stability and low cost make this core-shell structured Fe O @MnO a promising electrode material for practical applications in pseudocapacitors. 3 4 2 . . . .
