AbstractBirnessite-type MnO_2 (δ-MnO_2) nano-sheets were successfully synthesized by an interfacial synthesis method in this work. The properties and electrochemical performance of the as-prepared δ-MnO_2 were analyzed and evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD), nitrogen adsorption measurement and electrochemical tests. This facile synthesis method enables δ-MnO_2 nanosheets to show a large specific surface area (257.5 m~2 g~(–1)). The electrochemical test results show that the specific capacitance is 272 F g~(–1) and the specific capacitance retention is over 96.7% after 1000 cycles at a scan rate of 10 mV s~(–1). All results demonstrate that δ-MnO_2 has a great potential application in highperformance electrochemical capacitors, and this interfacial synthesis method will be a very promising method to synthesize highly active MnO_2 materials in a large scale.
