摘 要：A 3D porous carbon-manganese oxide（3D-C@MnO） nanocomposite is successfully synthesized via a thermal plasma deposition *** chemical bonds and compositions,phase structures,surface morphologies,*** as-obtained 3D-C@MnO nanocomposite were characterized by the various equipment,such as X-ray diffractometer,X-ray photoelectron spectroscopy,and electron *** electrochemical performances of the 3D-C@MnO nanocomposite electrode showed a specific capacitance of 780 Fg;at a current density of 2Ag;and a capacitance retention rate of 99% after 5000 charge-discharge cycles at a high current density of 10Ag;.These excellent capacitive performances may be attributed to the encapsulation of MnO nanoparticles by porous carbon sheets in the 3D-C@MnO nanocomposite *** is believed that the carbon-encapsulated MnO nanoparticles can be protected from a volume deformation during the charge adsorption/desorption cycle and can be electrically improved by the encapsulated carbon sheets,resulting in better overall capacitive *** addition,this study also demonstrates the practical applicability by assembling a supercapacitor using the as-obtained 3D-C@MnO nanocomposite to glow a light emitting diode.
