摘要：

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