Fig. 4
HRTEM images of bulk MoS2, MoS2 nanosheets, nanodiamonds, nano-onions, and nano-onion (NO)/MoS2 nanosheet composites with weight ratios from 1:1 to 1:8. Images of the forth column present nano-onion (NO)/MoS2 nanosheet composites with ratio. The fifth column and the sixth column present, respectively, the magnified images of NO and MoS2 nanosheet on the fringe of the nano-onion (NO)/MoS2 nanosheet composite from the image of fourth column. The red and blue arrows indicate the agglomerate NO and MoS2 nanosheets in composite form, respectively
