TEM and HRTEM images. (a) TEM image of the MnO2/CNT nanocomposite. (b) TEM and (c) magnified TEM images of a single CNT coated with a porous MnO2 layer. (d) HRTEM image of the interface between MnO2 and CNT. Inset in (a) shows the EDX spectrum of the MnO2/CNT nanocomposite. Inset in (b) shows the TGA spectrum of the MnO2/CNT nanocomposite. Inset in (c) shows the ED pattern of the MnO2/CNT nanocomposite. Inset in (d) shows the interplanar spacing of MnO2 nanoflake grown on the CNT.
