| Summary: | Single phase ZnO nanostructures were synthesized by a simple and low temperature solvothennal process from two different alkaline sources; Potassium hydroxide (KOH) and
Sodium hydroxide (NaOH) with zinc acetate dihydrate (Zn(CH3COO)2·2H20) as precursor. This facile and rapid synthesis technique achieve high purity of Zinc oxide (ZnO) nanostructures in large scale negating the use of complex and high temperature routes. The synthesized particles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Transmission Electron Microscopy (TEM), Energy-dispersive X-ray spectroscopy (EDX), Fourier Transfonn Infrared (FT-IR) Spectroscopy, and Ultraviolet Visible (UV-Vis)
spectroscopy. ZnO synthesized using KOH and NaOH exhibit wurtzite hexagonal and flake-like nanostructures with average crystallite size of 11.0 nm and 14.9 nm respectively. The optical absorption spectra of the two samples showed absorption bands of 367.70 and 365.30 nm. The results showed the effect of alkaline sources on the surface morphology, structural and optical properties of ZnO. |
