Résumé
The aim of the present study was the synthesis and characterization of copper(II) doped zinc oxide. The synthesis was done by solvothermal method, in 1-butanol or 1-pentanol, using only the acetate of the corresponding metal. The characterization of the obtained powders was done by X-ray diffraction (XRD), transmission electron microscopy (TEM), thermal analysis (TG-DSC), UV-Vis and fluorescence spectra (PL). The determination of the optical properties have indicated that while the UV-Vis absorbtion remains high, the photocatalytic activity is strongly diminished by the presence of the copper ions. Such nanoparticles are therefore best candidates for textile industry or cosmetic industry, where the usual photocatalytic activity of ZnO is a major drawback.
