Figure 1

Characterization of CNG samples.

(a) bright-field TEM images with the inset of electron diffraction patterns of CNG-DMF; (b) the high resolution TEM (HR-TEM) images of Co3O4 nanocrystals wrapped by graphene in CNG-DMF; (c) SEM images of CNG-DMF; TEM images of CNG-EtOH (d) and CNG-H2O (e); (f) the XRD patterns of CNG-H2O (I), CNG-EtOH (II), and CNG-DMF (III). The patterns of CNG-EtOH and CNG-H2O correspond to Co3O4 phase (JCPDS 9–418).
