Fig. 2

a Low-magnified and b high-magnified SEM images of CoO nanofibers. Size distribution of the nanofiber diameters is shown in inset of a. c Low-magnified TEM images of a typical single CoO nanofiber. EDX spectrum and electron diffraction patterns are shown in c, respectively. d High-angle annular dark field (HAADF) image taken from part of this nanofiber. Co and O EDX elemental maps taken from the sample region are also shown in d. e High-magnified TEM (HRTEM) image taken from the nanofiber
