A Simple Sonochemical Synthesis of Nanosized ZnO from Zinc Acetate and Sodium Hydroxide

Abstract

An efficient sonochemical route for synthesis of nano sized zinc oxide is reported. The method employs zinc acetate and sodium hydroxide as precursors with isopropyl alcohol as a solvent. As prepared powders were characterized by XRD, SEM and FTIR. These show that the resulting powder is composed of multidomain crystallites of ZnO wurtzite, zincite and Zn(OH)2. The XRD-measured coherent domain size varies from about 20 to 30 nm, whereas SEM exhibits  200 nm crystallites. The wurtzite phase is found to dominate at sonication times smaller than  30 min. It is also found that the powders produced sonochemically exhibit smaller and narrower size-distributed particles compared to that in hydrothermally prepared powders.

“…The carbonate anions (O-C-O) symmetric and asymmetric vibrations besides the lattice vibrations have also been reported [31]. The three spectra contain the absorption peaks between 1100 and 900 cm −1 which can be ascribed to Zn-OH vibrations [32] particularly the peaks at 1018.5 and 1020.7 cm −1 in FTIR spectra of zinc acetate precursor salt and ZnONPs, respectively, indicate the corresponding Zn-O bond vibrations.…”

“…The crystalline grain size (D) of GO was calculated using the Debye Scherrer equation [ 36 ] where λ = 0.154 nm, β = FWHM in radians and, θ = location of peak in radians.…”

“…The shallow peak at an angle (2θ) = 29.4 • (002) is attributed to graphite which is shifted to 10.74 • after oxidization of graphite to GO[35]. A broad peak at a range of 11 • to 28 • might be the sign of incomplete oxidation of graphite.The crystalline grain size (D) of GO was calculated using the Debye Scherrer equation[36] D = 0.9λ βcosθ where λ = 0.154 nm, β = FWHM in radians and, θ = location of peak in radians.…”

“…The average crystallite size (D) of RGO‐Cd 0.60 Zn 0.40 S‐Pt is estimated from the fitted XRD spectrum obtained using the Gaussian fitting. The average crystallite size is calculated applying the Debye–Scherrer equation to the fitted spectrum 47 where k is Scherrer's constant depending on the crystallite shape (0.89‐0.90), λ represents the X‐ray wavelength (1.5406 Å) provided from Cu(Kα) radiation, β is the FMWH (full‐width at half maximum), and θ is the angle of diffraction in radians.…”
