A variety of amorphous manganese oxide electrode materials with uniform nonspherical hollow interiors are prepared via sacrificial template-engaged redox etching of the corresponding shape-controlled Cu 2 O nanocrystals in KMnO 4 aqueous solution at room temperature. The obtained materials are characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy,...
The manganese oxide nanosheets (MnO 2 ) with negative charge and the functionalized carbon nanotubes (CNTs) with positive charge are selected as assembling blocks, and the manganese oxide nanosheets and functionalized carbon nanotubes hybrid material (CNTs–MnO 2 hybrid material) is fabricated by an assembling flocculation method. The restacking process of the manganese oxide nanosheets...
