摘要

Copper-decorated carbon nanotubes (CNTs) have important applications as precursors for ultraconductive copper wires.Tenorite-decorated CNTs (CuO-CNTs) are ideal candidates and are currently developed using laborious processes.For this reason,we have developed a facile and scalable method for the synthesis of CuO-CNTs from copper acetate.It was found that the optimal loading of copper acetate onto the CNTs was 23.1 wt％ and that three 1-minute microwave treatments were sufficient for the decomposition of copper acetate to copper oxide.The loading of copper oxide onto the nanotubes was confirmed using X-ray photoelectron spectroscopy,energy-dispersive X-ray spectroscopy and thermogravimetric analysis.The materials were characterised using X-ray diffraction and scanning electron microscopy.
