Images of Ag/MWCNT taken by different imaging devices. (a) Scanning electron microscope [SEM] image of a Ag/MWCNT that the MWCNT is completely covered by silver layer. (b) Energy-dispersive X-ray spectroscopy spectra of the Ag/MWCNT that no oxygen can be identified. (c) SAED pattern shows a multicrystal structure in Ag/MWCNT nanowire (d) HRTEM of the silver coated onto a MWCNT of the Ag/MWCNT nanocomposite. Arrows show the crystal orientation.
