The invention discloses a kind of CuO@MnO 2 Core shell structure porous nano wire material and preparation method thereof, the CuO@MnO 2 The stratum nucleare of core shell structure porous nano wire material is CuO nano wires, and shell is MnO 2 Nanometer sheet, and CuO nano wire dense growths are in substrate, and shell MnO 2 Grow nonparasitically upon another plant in CuO nanowire surfaces nanometer sheet dense uniform, and crisscross, loose structure is formed in nanowire surface.Preparation process includes that aoxidizing the prepared surface length of copper mesh has the copper mesh of CuO nano wires and pass through in KMnO 4 It is MnO that in solution, short time hydro-thermal process forms shell on CuO nano wires 2 Nanometer sheet, ultimately forms CuO@MnO 2 Core shell structure porous nano wire material.CuO@MnO obtained in of the invention 2 Generate new nanotopography, it is a kind of new heterojunction structure, and causes new interface, and huge specific surface area significantly increases the avtive spot of reaction, so as to the response characteristic of the nano composite material can be lifted, its application prospect in energy storage, catalysis and sensory field is expanded. |
