Abstract

 Application of the green chemistry in preparation of nanomaterials has been developed and replaced instead of toxic solvents and reagents. ZNO NANOPARTICLES have been synthesized via a novel GREEN CHEMISTRY METHOD using a water soluble N-SULFOSALICYLIDENE GLYCINATO ligand. For this purpose, the inorganic complex, Zn/N-sulfosalicylideneglycinato water soluble ligand has been prepared by the condensation reaction of glycine amino acid with sulfosalicylaldehyde in the presence of zinc salt. Then ZNO NANOPARTICLES have been synthesized by the THERMAL DECOMPOSITION of inorganic complex precursor at temperatures of 400, 500 and 600 °C. The products were characterized by XRD, PL spectroscopy, UV-vis spectroscopy, STA, FT-IR, SEM and TEM. The results confirmed that ZNO NANOPARTICLES were synthesized in water based medium, in the wurtzite phase and spherical morphology with the average particle size of 35-45 nm. The band gap energy was achieved about 3.2 which is 0.17 units less than that of the bulk ZnO.
