Assembling tin dioxide nanorods on carbon nanotubes by a chemical solution method

ABSTRACT

Nanocomposites have significant potential in development of advanced materials and nanotechnology applications. Here, multi-walled carbon nanotubes (MWCNTs) sheathed with tin dioxide (SnO₂) nanorods by a two-step chemical solution route are reported. Hydrolyzing of MWCNTs and SnCl₄·5H₂O at a near room temperature followed by alkali-assisted hydrothermal process resulted in perfect SnO₂ coating on MWCNTs. Based on the XRD and TEM results, we found the nanoscale SnO₂ rods covered densely on MWCNTs.
