One-Step Route to Synthesize Multiwalled Carbon Nanotubes Filled with MgO Nanorods

الملخص EN

Multiwalled carbon nanotubes filled with MgO nanorods were synthesized through the reaction of ethanol and Mg powder in the presence of TiO2 at 400C°.

X-ray powder diffraction indicated that the sample was composed of graphite and cubic MgO.

Transmission electron microscopy studies showed that multi-walled CNTs with the outer diameters of 70–130 nm were filled with discontinuous MgO nanorods whose diameter was in the range of 25–40 nm.

The ratios of the band intensities (ID/IG=0.67) in Raman spectrum implied that carbon nanotubes had good crystallinity.

The influence of correlative reaction factors on the morphology of the sample and the possible formation mechanism were discussed.
