Abstract
In this study, a glucose-assisted method has been developed to prepare CoTe nanotubes using Te nanorods as the in situ templates under hydrothermal conditions. It was found that the concentration of glucose has an important influence on the morphology of the products. The average inner diameter of CoTe nanotubes can be adjusted from 60 to 20 nm by changing the quantity of glucose from 0.5 to 1.0 g. The samples are characterized by means of X-ray power diffraction (XRD), field emission scanning electron microscopy (FESEM), X-ray photoelectron spectra (XPS), selected area electron diffraction (SAED), and transmission electron microscopy (TEM). The formation mechanism of the CoTe nanotubes is discussed based on the experimental results.
