Synthesis and characterization of ZnO nanoparticles - comparison of acetate (precursor) based methods

This study was formulated to synthesize the ZnO nanoparticles through acetate-based zinc salts with NaOH (ZnO-I) and Oxalic acid (ZnO-II) as reactants; sodium dodecyl sulfate (SDS) used as a stabilizing agent in both the protocols. The derived results indicated that the X-ray diffraction pattern of images showed that particles were highly crystalline (wurtzite) in nature with an average size of 43 nm to 45 nm, respectively. SEM and TEM images exhibit that nanoparticles were spherical shape with flatten morphology and size of 100 nm with mild agglomeration. The FTIR pattern depicted the absorption spectra bands at 486 cm(-1) confirms the presence of Zn-O stretching in both the particles. The EDX analysis shows the atomic % of zinc and oxygen was 61-64 and 32-34, respectively for the ZnO-I and II. The acetate based precursor with oxalate reactant calcined at 400 degrees C recommended for desired size and more recovery of ZnO.
