Sonochemical Synthesis of Nanocrystalline Copper Tellurides Cu7Te4 and Cu4Te3 at Room Temperature
Source abstract
Abstract
In this paper, we report a simple and clean method of producing nanocrystalline copper tellurides in an organic solvent system by high-intensity ultrasonic irradiation at room temperature. Cu 4 Te 3 is prepared in a pure ethylenediamine system and Cu 7 Te 4 is prepared in ethylenediamine with hydrazine hydrate. The products are characterized by X-ray powder diffraction (XRD), transmission electron microscope (TEM), and X-ray photoelectron spectra (XPS). Ultrasonic irradiation and the solvents are both important in the formation of products. The formation mechanism of the nanocrystalline tellurides under high-intensity ultrasonic irradiation is also discussed.
