    Morphology and Electrical Capacitance Characteristics of Nanostructured MnxOy/MWCNT Composites

    Reducing potassium permanganate by a carbon matrix (multiwalled carbon nanotubes (MWCNTs)) in aqueous solutions, we have obtained MnxOy/MWCNT nanostructured composites (NSCs). The morphology and texture of the MW...
