Hollow Co<sub>3</sub>O<sub>4</sub>@MnO<sub>2</sub> cubic nanomaterials are synthesized by ZIF-67@Mn-ZIF sacrificial precursor through a facile thermal treatment. As a kind of supercapacitor electrode material, it demonstrates high performances, such as specific capacitance of 413 F g<sup>-1</sup> at the current density of 0.5 A g<sup>-1</sup>; as the current densities raised from 0.5 to 10 A g<sup>-1</sup> (20 times increasing), there is still ~41% retention of its initial capacitance. These sat ...[more]
