A new one-step synthesis method for coating multi-walled carbon nanotubes with cuprous oxide nanoparticles

A new method was developed for the synthesis of Cu2O-coated multi-walled carbon nanotubes (MWCNTs) on the basis of Fehling’s reaction. The method involved dispersion of carbon nanotubes in Fehling’s reagent, followed by addition of formaldehyde as a reducing agent. The Cu2O-coated MWCNTs were characterized by transmission electron microscopy, X-ray diffraction, X-ray photoelectron, Raman and UV–Vis spectroscopy, and superconducting quantum interference device measurements. These novel materials could be used in catalysis and optoelectronic applications.
