Abstract
Undoped and Cu doped ZnO nanoparticles (Zn1−xCux O) with x = 0.0, 0.01, 0.03,
0.05 and 0.07 were prepared by Solvothermal method at 130°C. Structural and thermal
properties of samples were investigated by X-ray diffraction (XRD), thermogravimetric,
differential thermal analysis (TG/DTA) and FTIR spectroscopy. XRD analysis
confirms that all samples have hexagonal structure with no impurity phases, which suggest
that Cu ion successfully incorporated into the ZnO crystal structure. The lattice
parameters, volume of unit cell,and cristallite size were calculated from XRD pattern
of samples, and it was found that the average cristallite size was in the range of 26 nm
to 46 nm. The TG and DTA measurements gave us information about the thermal
transitions. The TG and DTA measurements confirmed the purity of the synthesized
ZnO / ZnCuO nanopowders, and showed that the loss of mass, which corresponds to
the various endothermic and exothermic peaks, corresponds to the evaporation of water,
alcohols, groups of nitrate, acetate and Monoethanolamine. The functional group
and chemical interactions of (Zn1−xCux O) samples were also determined at various
peaks using FTIR data.
